![]() ![]() It make sense outputing to a higher bitrate when converting to mp3 or When a certain file (mp4, flv, etc) has a 95 kbps audio bitrate - does (is it aac?) (- And in general the answers seem to fall in one of the two positions represented by the most voted answers.) The most voted two answers below ( this and this) seem to say different things, namely, the later says that Bitrates are not directly comparable and if the original audio is in a more efficient format, then the output ( less efficient) audio should have a somewhat superior bitrate (the same idea here and here) - but while the less efficient is mp3, I am not sure which exactly are the more efficient formats. Maybe a sub-question is useful: is the answer dependent on the type of the output file (lossless or lossy)? The question is just about the usefulness of optionally increasing the bitrate when converting. Only that in some cases an original cd/wave may be unavailable. Please consider that I am aware that converting between lossy formats is not recommendable. (Except for going from a lossless format to the original wave.) I am talking whether an output with a higher bitrate than the input will have a better quality than it might otherwise have. I am not talking about the output having better quality than the input: obviously, that is not possible. Would this result in higher audio quality or just in a bigger file? When a certain file (mp4, flv, etc) has a 95 kbps audio bitrate - does it make sense outputing to a higher bitrate when converting to mp3 or other format (be it lossy or not)? Answers without enough detail may be edited or deleted. It extracts the audio from the video as it is, which is what Audacity does when using FFmpeg, before Audacity expands it into PCM audio so it can work with it.Want to improve this post? Provide detailed answers to this question, including citations and an explanation of why your answer is correct. Demuxing is not conversion or re-encoding. If you don’t want to use the audio in Audacity at all, you can find a tool to demux the AAC audio from the video. Then you can import the video file into Audacity and Audacity will extract the audio from the video without making the quality any worse than it already is. When you have the downloaded video file, you can add FFmpeg to your computer: Audacity Manual. Don’t choose any option in the extension to download as MP3 because it is a lossy conversion, not the original file. You can obtain extensions for all the major web browsers that download the file that is on the server. Use your favourite search engine to find how to do that. Then you don’t lose any quality compared to the file that you hear in your web browser. So the best solution of all is to download the video file that is on the server, in the highest quality available. You still lose a little quality by converting from digital > analogue and back to digital during the recording process, and you may record system sounds that happen while you’re recording. It would be better to record the YouTube song into Audacity ( see Tutorial - Recording Computer Playback on Windows ) than to download the song converted to MP3. ![]() When you export as MP3 from Audacity that is another stage of quality loss. ![]() If you use a tool to download the audio of the song as MP3, it is converting the file, so you lose quality by that conversion. The YouTube files are stored on their servers as MP4 (or FLV or 3GP) video files. I have an on-line converter but the quality is to low (96kbps).ĭownloading as MP3 is the worst possible choice. Sometimes i see a music clip on you tube and will download this as an mp3. ![]()
