What is the best way to transcode audio and video to show on the web? I need to do it programmatically. I'd like to do something like YouTube or Google Video where users can upload whatever format they want, and I encode it to flv, mp3, and/or mp4. I could do it on our server, but I would rather use an EC2 instance or even a web ser...
What is the best way to retrieve mp3 metadata in python? I've seen a couple frameworks out there, but I'm unsure as to which would be the best to use.... Any ideas? ...
What is the best way to get and set the meta data for mp3, mp4, avi files etc. with .NET? ...
I'm about to start a project that will record and edit audio files, and I'm looking for a good library (preferably Ruby, but will consider anything other than Java or .NET) for on-the-fly visualization of waveforms. Does anybody know where I should start my search? ...
Original Question I want to be able to generate a new (fully valid) MP3 file from an existing MP3 file to be used as a preview -- try-before-you-buy style. The new file should only contain the first n seconds of the track. Now, I know I could just "chop the stream" at n seconds (calculating from the bitrate and header size) when delive...
For years, I've been investigating how to create music streams from my computer. I've seen programs, but anything useful I've seen is windows only (I use a Mac). Eventually, I got interested in how streams work. Is there any way I could create my own stream, possibly using socket functions in PHP? Is there a PHP library for this? Th...
Can anyone recommend a good library for generating an audio file, such as mp3, wav, or even midi, from python? I've seen recommendations for working with the id tags (song name, artist, etc) in mp3 files, but this is not my goal. Thank you very much! ...
I want to put songs on a web page and have a little play button, like you can see on Last.fm or Pandora. There can be multiple songs listed on the site, and if you start playing a different song with one already playing, it will pause the first track and begin playing the one you just clicked on. I think they use Flash for this, and I co...
I'd like to write a program to clean up my music collection and it would be nice to be able to query a webservice for song and album information. I'm not really thinking of a cddb/freedb type of situation where you hand them a hash based on the number of songs and the lengths, etc. I'm really thinking more of "hey, for this album from ...
Dear All, I'm wondering about MP3 decoding/encoding, and I was hoping to pull this off in Flash using AS3 I'm sure it'll be a right pain... I have no idea where to start, can anyone offer any pointers? reference material? ----much later--- Thank you all very much for your input... It seems I have a long road ahead of me yet! ...
I've got many, many mp3 files that I would like to merge into a single file. I've used the command line method copy /b 1.mp3+2.mp3 3.mp3 but it's a pain when there's a lot of them and their namings are inconsistent. The time never seems to come out right either. ...
Hi, I'm looking for a way to extract the audio part of a FLV file. I'm recording from the user's microphone and the audio is encoded using the Nellymoser Asao Codec. This is the default codec and there's no way to change this. DISCLAIMER : I'm not attempting to do anything illegal (like stealing copyrighted content...). This is a bus...
What's a quick and easy way to view and edit ID3 tags (artist, album, etc.) using C#? ...
I've been looking for a way to convert an mp3 to aac programmatically or via the command line with no luck. Ideally, I'd have a snippet of code that I could call from my rails app that converts an mp3 to an aac. I installed ffmpeg and libfaac and was able to create an aac file with the following command: ffmpeg -i test.mp3 -acodec lib...
I'd like to know a good ID3 tag reader library for Java. Would be good if it was easy to use or had very good documentation, but my main criteria is speed - I want to be able to read ID3 tags from over 10,000 files as quickly as possible. Edit 04-Jan-2010 I'm not entirely sure what to do with this question now - it was a high priority ...
I need an encoder that can convert mp3 files to he-aac (aka aac+). So far the best one I have found is nero aac encoder . I have two problemes with it : - Only one input format : wav . It is a little bit slow to transform mp3 files to wav and then to he-aac. - a free license for non commercial use. Too bad ffmpeg does not support h...
Hello all! I am writing my masters thesis which is closely related to processing sound files (mp3 and alternative formats such as ogg, aac, ...) and sound in Java. Because Java has so much open source support, I didn't think I would have any problems in finding everything I need already coded, but so far results are very sparse. I want...
I've written a simple Flash player for a Shoutcast stream. At first it seemed to work reliably, however about 5% of the time users experience slow playback where the stream plays at roughly half of normal speed. All files being streamed are MP3, encoded at 128kbps/44.1kHz, the same settings as used in the Shoutcast config files, so the ...
What version control systems would be useful or have extra features to support projects that are mainly binary files like mp3, wav, or proprietary application-specific file types? ...
What is the simplest way to determine the length (in seconds) of a given mp3 file, without using outside libraries? (python source highly appreciated) ...
