Is it a good idea to upgrade my mp3 music collection to flac?
If by upgrade you mean converting your current collection to FLAC no it's a bad idea you'll just be wasting memory space. At the creation of your MP3 files certain data that were part of the initial raw files have been thrown away. Converting MP3 to FLAC (which would have kept more of the initial data) is not advisable since the data that makes FLAC better is absent in the MP3. However if by upgrade you mean replacing your current MP3 collection with original FLAC files then by all means go for it. If you're someone who has an excellent taste in the quality of music material FLAC WAV or any other upressed audio file format will serve you better. You get to enjoy the dynamics of the music material more with each of those.
Is there a way to convert an audio file (mp3 or wav) to a MIDI file?
This is a tough problem. A good analogy is converting speech to s. A wav file is pretty much like speech with all theplexities of sound and midi is like words on a page a short hand that captures the essence but lose the details. The task of converting them is much the same. You listen to the different instruments and transcribe them note by note. It's painstaking but a skill that is practiced in musical schools called ear training. If it seems impossible with practice it can be quite doable. Regardless it's much easier if you can start with sheet music then it's like translation between to similar languages. There are several free programs out there that can use 'audacity to help select little sections of a wav file an listen to them repeatedly. Also I can isolate the left and right stereo channels and that can help isolate an instrument I want to focus on. MuseScore is software I use to help write the midi notation. Downloading a pitch analyzer plug-in for audacity can help you hmm a note back to identify it. Many other free software packages are out there this is a highlight of options s Lastly there is a piece of pay software called transcribe from seventh strings that claims to do the whole job. I've never used it but regardless I bet you it would only get you so far. A few other tips look for other versions played by a single instrument solo's acoustic or kareoke. Again look for sheet music. Lastly look into learning a bit of music theory regarding and ear training. I've been advising as if a bit of theory was assumed. So make sure you know the basics! Nothing crazy but the more you know about theory the easier the task.
Can humans hear a difference between low bitrate and high bitrate MP3s?
Quick answer nYes. On decent audio equipment with a familiar song that has been well-produced it's easy to tell the difference between 128kbps CBR 192kbps CBR and anything in the 32kbps CBR v lossless range. Detailed answer n Can humans hear the difference between 128kbps and 32kbps mp3? italic nYes the difference between 128kbps and 32kbps CBR mp3s is very noticeable with most music but it depends on the source. Some music sounds absolutely terrible even off of the CD (for example Metallica's Death Magnetic was a terribly mixed album that will sound bad no matter what). If we establish that we have a good source then we can get to encoding quality. Riley Patterson user 2215111 posted a in the questionments to a non-scientific study on Jeff Atwood topic tid 612 's Coding Horror blog that suggests that anything 16kbps and above is indistinguishable. It did however only use one song which could have had a terrible source! Hardly conclusive. If the music is recorded poorly mixed poorly I'm on a pretty low-end and bad for listening setup at home right now with the musicing from my desktop pc's onboard sound to aputer monitor to AKG K24S headphones but it's a clear difference even on this setup. With a pair of stock iPod earbuds while going for a walk? Probably wouldn't know the difference. On a 2.1 set of $1puter speakers? no way. But on any decent listening setup the difference is clear. The 128kbps mp3 has little to no depth of sound with everything sounding a little flat; high hat and cymbals sound harsh and manufactured guitars sound like they might as well have been synthesized and the sound stage greatly diminishes. Try these 5-second samples. One is the quality of a 128kbps mp3 the other is lossless qualitynA nEven on my relatively lousy setup on an unfamiliar song I could tell within 5 seconds that the first one I listened to was lossless without checking the other. See if you can tell the difference on your set up! (and let me know what you think in thements). I don't think I have dog ears or better than average hearing at all just a decent pair of headphones. Can humans hear the difference between 192kbps and 32kbps? italic nNow when you get to higher bitrates it bes a little more tricky. 192kbps is definitely good enough for most people in most situations. A good portion of my music is 192kbps because I couldn't find it any higher or I didn't want to bother re-ripping my old cds. Even on an excellent set-up it won't be hurt your ears bad the way some people claim 128kbps can be. On a good set-up though actively listening to familiar music you can hear details in the music in lossless and near-lossless quality that you won't be able to or won't stand out as much at 192kbps. Maybe it's not something that everyone can hear but I believe anyone who pays attention to their music and is listening to a good enough source can tell the difference. Can humans hear the difference between 32kbps and lossless? italic nI doubt there are many people in the world that can tell the difference between a 32kbps mp3 and a lossless track. The reason that FLAC and other lossless codecs are important is not because they provide the best sound quality for listening but because they are useful for archiving. If you only have 32kbps CBR mp3s and a new codeces along that is 1 times more efficient (lets call it xyz) then you're going to be transcoding (going from a lossy format to a lossy format) from mp3 to xyz files. Even though the audio quality difference between a FLAC file and a 32kbps mp3 is hardly if at all noticeable there is data lost in that conversion. Whenever converting to a new file format it's always important to start from a lossless file. It's hard to know what other people hear and I'm certain different people having different perceptions of music is what leads to some of the debate around the topic. I hope to have shed some light on the issue with my answer; having spent a decent amount of time talking to other people about the subject being a lurker on Head-Fi for a couple of years and owning a few decent pairs of headphones and a lot of music I feltpelled to give my experience and understanding. I'm not aware of any really good studies that have attempted toe up with definitive ranges of perception around the subject but would love to hear if someone else has read one.
If I convert mp3 (192kbps) to m4a (256kbps), will the quality be better?
No. There are two parts to the answer. First m4a files are container italic files not audio files. The audio contained in them can be of different encodings including AAC mp3 and many others. So if you were to convert a 192kbps mp3 to a 192kbps m4a the audio after conversion would be identical because the audio part of the mp4 file is still mp3. Second you cannot improve audio quality of an already-encoded file by converting it to a higher bit rate. If you took the same source audio and encoded it as both 192kbps and 256kbps then decoded them both back to analog the 256kbps version would be higher fidelity* - i.e. more accurate - than the 192kbps version. This is because the analog audio is sampled more often in the higher-rate encoding process. However once you have digitized the audio the analog information between sampling times is lost. Decoder software may interpolate between samples but these interpolated values are not guaranteed to be the same as the values in the original source audio. So converting from an mp3 file at 192kbps to one at 256kbps means that the interpolated values rather than the original audio values are encoded in the upsampled file. *If you can hear the difference between mp3 audio at 192kbps and 256kbps you have truly excellent hearing. A bad-sounding 192kbps mp3 is likely due to other factors in the audio chain not the encoding.
What are the best Python scripts you've ever written?
I am aputer engineer with 15 years of experience. I have created multiple python scripts (similar to many scripts described already ) for daily usage tasks. However my best python script would be facebook automation. The setup includes a selenium driver on firefox. The script is triggered once every 6 hours on a dedicatedputer. The scripts opens web browser and logs in with my account. Some of thing it can do are listed Parse my full friend list and create an xml with all relevant details. (This is important as later steps take action only on feeds from people in this created xml.) Scroll the feedpage and take actions on individual feeds. By default it will like any profile pic cover pic change. If other people congratulate my friend it can parse thement like the feed andment congratulation message. I am anonymous because most likely it against facebook policies to use this kind of scripts for daily interaction. EDIT 1 This edit section is for people who are interested in knowing how the whole script works. I will try to keep it minimal so that it doesn be too technical. The script has 3 main work areas Navigation Navigate to a webpage scroll the page etc. Action Take some action on specific element based on info collected. ordered-list Navigation Selenium driver gives the direct capability to launch a browser navigate to a scroll down etc. Hence this part is pretty much straight forward. Info collection This is one of the most hard parts. On firefox you can right click any element and inspect it . Inspect Element gives details of what the html code for an element looks like Here is a snapshot of what firefox shows when i inspect a friend name in my friends list. The class of div element is very important. I now know that whenever i will parse an element of this class it will have the details of my friend (name etc ) I first statically find these elements manually and then hardcode them in my script. I can now parse necessary elements and collect the information present in those via selenium. Selenium gives the api to extract each information of an element. For e.g. I can extract the href in above picture and i can save the of my friend. This example also covers first point of my script of how i created xml of all my friends. I need to parse my friends list only once and save it for future use until i add a friend. In a similar way we can parsements count events etc . Action Once we have collected the information we can apply our own programming logic to that information. For e.g if someone hasmented Nice picture we can post a similarment. Selenium provides the api to click on element in a area etc. So for like we simply click on Like element with that specific class. That all folks.
What are 5 habits that can improve my life?
I'm going to write these in order of what you probably haven't seen 15 times already because I know when I read the same thing over and over again it makes my soul sad. Get rid of your phone whenever possible. 3. Do the hardest thing you dread doing immediately after finishing the morning routine . Get some work in on it. If nothing else working on and getting some of this hard thing done will make you feel good afterwards and give your day some meaning already. This is in contrary to doing small things first like checking emails. Which can just lead to procrastination and ultimately failing to ever do the hard thing that day! Read the book The War of Art by Steven Pressfield to develop a healthy mindset about procrastination and how we must fight it every single day. 4. If you notice youre getting into a funk and feeling not yourself don't just keep doing the same thing for weeks! Try different things to fix it! Mental health is everything. Disclaimer I'm not a medical professional or mental health professional. I'm simply sharing what's worked for me. I always get into funks and havee up with creative ways toe out of them to find out what's causing it. You can't fulfill your dreams if you feel like shit. I've found sometimes there's no fix-all solution that you want to start doing every single time you feel bad because then you'll get addicted to it and start needing it to feel happy. Rather have a toolbox of things you can try when you're feeling blue and know yourself enough to know which one to use. Here's a few of mine High intensity exercise. From a biological standpoint our bodies are meant to be worked chasing elk with spears and shit. If we never use it well feel like crap. Go to a gym (try and find one that has a sauna too). Sweat it out. Take a long run do some weightlifing play racquetball or basketball for an hour. All of this can snap you out of a bad day. If you arent that athletic hire a personal trainer or take a group exercise class. Bonus points because you can't really get addicted to working out so you can do this every day. 1 Your body is that thing you have to live in all the time. If you aren't taking care of it you're going to feel like crap for sure - this involves eating well too. 1 Disclaimer I'm not advocating anyone go out and do the following I'm simply sharing what's been useful for me italic . Do italic your own research. Also be aware that the following may affects some people negatively. italic Sometimes we get into a bigger funk than just feeing off for a day something deeper. Waking up and working each day bes so monotonous. Oh .. .what's the point? We feel trapped. Maybe we aren't achieving as much as we hoped as quickly as we hoped. Psychedelics and mini-nature-vacations every once in a while can be useful to snap out of a negative brain loop and get some positive perspective on this beautiful world we live in. Ive avoided mentioning this publicly for a long time but with Tim Ferris and others publicly acknowledging the benefits of psychedelics I feel like less of a weirdo mentioning it. 1 Heading out to nature for a night or for the weekend and scrubbing things clean with a small bit of psilociblin (the active ingredient in magic mushrooms) can help snap out of a funk. Sometimes these negative thought patterns just keep replaying and replaying in our brains that aren't serving us- that we need to break free. This helps to do that. There's also a lot of people in Silicon Valley talking about microdosing LSD. I would advise against doing any of this regularly but if you're getting into a funk and it helps . well. If it works it works! 1 Realize that if you can keep your mental health in check that's all you need. If we can be in a positive happy and creative state and put in the hours of work everyday good things are bound to happen eventually. Our belief and attitude affects our choices and thus our entire life and ability to produce awesome stuff. If you want to achieve keep yourself sane. 1 Sometimes a sober nature trip or other short 3-day vacation to someplace new in itself can be much needed (no caffeine even!). A detox from everything you normally do. Sometimes were doing something every day that's leading us to not feel good and we don't even realize it. Do you drink caffeine every single day? Maybe eat the same food each day? Or see the same people? Get away from it. Go to a new place you haven't seen before. Snap out of the mold. 1 Ideally you want to be running on natural fuel. You wake up eat healthy exercise and work on things that make you happy and contribute to the world. That should be the norm. These other things are just for when you get in a funk. We aren't taking adderall every day. We aren't drinking 12!coffees every day. We arent taking psychedelics every day. Those are tools. Fall prey to needing them to function and they will own you. 1 I advise against going out and getting wasted at a bar or club when you're feeling down. I've found this usually doesn't work. 1 Whatever you do italic try and get your thoughts together and think about a plan for when you make your return to work and the routine. Example - okay I've been feeling shitty. This little time away at the beach is nice though. Here's my plan of attack when I return going to start on project X. 1 5. In general stop chasing the opposite sex . Don't feel iplete if you aren't dating someone all the time. Because I can tell you dating is just a skill like anything else. You can put time and learn it but I guarantee if you spend all your time doing it then. Well let's just say your time would be better spent by really creating something beautiful and meaningful that other people in the world can enjoy. Like a business or creative projects or hobbies. Or art! Put your energy into those. If you're a dude don't put tons of time into trying to hook up with girls all the time. Same if you're a lady whose always looking for Johnny toe make her lifeplete. If you find your passion or at least something that gives some meaning to you give yourself to it. Set up a balanced life with good friends and good energy good habits and you'll feel good that way. And guess what? Other people will feel how whole and happy you are and will gravitate toward you! You won't have to chase them. You can organically meet people also pursuing the same interests. One caveat here - if you're a person with low self confidence and insecurities perhaps do some self help on that! It will build character and confidence. I was deathly shy in middle school and highschool and had to do a lot of hard work and learning to bring myself out of my bubble. Until I did this there was something missing. Get into conversations with strangers or that cute girl or guy at the coffee shop. Get out of yourfort zone. Do things that may seem scary that you I haven't tried before. Because in 7 years you'll be dead. Do you think anyone will care that you walked up to that cute girl and made a bit of a fool of yourself? No! Nobody cares. Only your own ego cares. If you can't walk around in your day to day life and smile at the people you pass by if you're scared to interact with strangers or talk to that cute girl then do some work on it! It will build your confidence. I am a huge proponent of facing fears. Once you have a bit of experience under your belt then it's easier to say Okay dating world. I'm going to focus on my craft now. But I know I cane back to you when I'm ready. That's all for today.
What are the best Windows audiobook players?
Consider Angel's Vox ($) or WorkAudioBook (freeware). WorkAudioBook is more up-to-date of these two (plus it's free though it requires free registration) as its latest version (as of writing of this) was released in November of 215 whereas the latest version of Angel's Vox was released back in 211. WorkAudioBook only supports Mp3 format so if your audiobookes in m4b format you would have to convert it to Mp3 format first (using something like ImTOO Audio Converter Pro ). Or if you acquire your audiobook from Audible you'd have to remove the DRM first ( see my blog-post for the details s ). iTune is as good audiobook player as any program capable of playing Mp3 files (like Audacity or any number of Mp3 players and sound editors). My favorite (for listening to Mp3 format music) is foobar2 s . But Mp3 players and editors have one major flaw when ites to listening to audiobooks they don't allow bookmarking and they don't remember where you left off. WorkAudioBook has bookmarks system and it also remembers your current position in an audiobook (even when you switch between different audiobooks in case you're listening to multiple audiobooks concurrently). A side-note On Android side the best audiobook player hands down is the excellent Listen Audiobook Player s (cost $1.5) and for iPhone look for Bookmobile Audiobook and Podcast Player s (full-featured $).
Why would my husband have an MP3 app that changed videos to audio?
Why would my husband have an MP3 app that changed videos to audio? Ever been looking for that one old song that you loved as a child? Sure you can buy it on CD but then youll just get themercial remix while you just want to have the same version you loved. Remember the time you could carry your Walkman around in your pocket with a few tapes? Basically you had your own radio station with you. The main nuisance was having to rewind or fast forward a lot and it wasn very precise so it could take a while if you wanted to hear the entire song. Then came that new innovation the DiscMan. Way to big for your pockets so you would like to go with a robust model. Still you would have to take several CD with you if you weren planning on listening to the same 12 songs all day. Then lo and behold Even when they were still big MP3 players easily fitted in your pockets but the best of all you could fit hundreds upon hundreds of albums on them. Sweet huh? Now an average mp3 file is about 1MB minute. A video file will be bigger after all it has to contain more information. Information that is pointless if you plan to just listen to the track. Several mp3 players might work with different formats including video files but it takes up space that could be used for other songs and it isn sure the mp3 player (or app on which your husband wants it to play) supports video files. Basically your husband is just glad he can listen to his favorite music without being bothered with what he s not interested in. He strips the video so minimal data storage and gets what he after.
