Is there any difference between original sound and converted lossless?
Hello!
I use Audacity in Xubuntu 14.04 LTS. Audacity can't import a lot of formats, for example: aac, ac3. But it can import .wav. So, is there any difference between these two methods?: original sound -> import -> edit -> export original sound -> convert to lossless wav -> edit -> export. I use ffmpeg so the second method isn't more complicated. ffmpeg -i source.mkv -c:a copy out.ac3 ffmpeg -i source.mkv -c:a pcm_s16le out.wav |

Audio editors (Audacity, SoundForge, etc.) work with uncompressed audio like wav files are. Then Audacity 'read' wav files without any operation. Compressed audio, lossless (Flac, etc.) or lossy (Ac3, Aac, etc.), must be decoded before to be edited. Then Audacity need 'decode' compressed formats, and can use ffmpeg (and others decoders) automatically to 'import' these formats. Many Audio editors have decoders, inside or by plugins, to decode compressed formats. Quote:
But you can decode these formats to wav with others decoders (eac3to, BeHappy, ...) and after read the wav with Audacity.
