Concatenating MP3 files

由 强颜欢笑 提交于 2019-12-12 04:09:04
问题 Seeing as how MP3 frames are (mostly) independent units, I thought it would work well to simply concatenate several tagless MP3 files together in order to merge them losslessly.

Whatever this information is, I'm sure it can't be too hard to write a

由 感情迁移 提交于 2019-12-12 03:35:05
问题 Please note This is NOT a duplicate of the other question linked. That uses classes I couldn't find, as detailed in my question below. I'm trying to convert wma files to mp3. I need a solution that I can integrate into my code base, not rely on an external resource, so using ffmpeg isn't an option. I've been trying NAudio, but without any success. One problem is that there seem to be two versions of NAudio around, and neither seems complete. The one you get from Nuget doesn't include the

问题 I have mp3 and wav audio files. I want to divide them into smaller files programmatically.

Seeking the silent segments can be done by scanning

Howler.js doesn't recognize src path to audio file

由 一个人想着一个人 提交于 2019-12-12 01:25:59
问题 After successfully playing an audio file with the HTML5 built-in audio tag, I'm trying to switch to use howler.js instead. I've verified that howler.js is properly installed and that the method which creates/plays my song is being called with a console.log, but I'm confused as to why the path isn't recognized here: new Howl({src: ['../music/lofi.mp3']}) while the same path works just fine here: <audio autoplay> <source src="../music/lofi.mp3" type="audio/mpeg" id="track"/> </audio> export
