160K opus vs 320K mp3 vs 256K AAC
Doesn't take the Library of Congress - by the way, they prefer WAV and TIFF files instead.
But as for your OP >>52450648
160k Opus if you're a freetard and believe in meme magic
320kb MP3 if you want the best quality out of the three options*
256 AAC if you plan on putting these on an iPod.
* Has a cutoff at roughly the top end of human hearing ability, 19-19.5kHz
All those converted at those exact bitrates through ffmpeg from the FLAC source.
FLAC is lossless compression, but encoding into it takes time. Most pressed audio CDs use WAV, so that's what they stick with. TIFF too, because there is "more to it" as of now than PNG.
Perhaps, but only on /g/. Spectral analysis is in order. I suggest SoX.
Interested in this.
What is best codec used for ASMR?
I usually download from youtube with ytdl using the extract audio parameter, to get m4a format or webm format and the n use the atomicparsely to include the thumbnail as an image.
So what's best argument do I use to get smaller file size while preserving quality and the stereo output?
For archival: FLAC.
For listening purposes: All three should be transparent to almost all audio, so pick the one which uses the least space to become transparent, which is Opus 1.1 @ 160kbps VBR: opusenc --bitrate 160
