Audio Compression Comparison

Описание: In this video I demonstrate what MP3, WMA, Vorbis, AAC and Opus sound like at 32, 64, 96, and 128 kb/s. Encoded using FFmpeg from 24-bit FLAC source. Note that for some of the higher bitrates, YouTube's audio compression may affect what they sound like.

Download video with FLAC audio (to bypass YouTube audio compression):
4K60 (MP4 container): https://drive.google.com/file/d/1HEbx...
4K60 (MKV container): https://drive.google.com/file/d/1sF0C...
720p30 (MP4 container): https://drive.google.com/file/d/1DTs5...
720p30 (MKV container): https://drive.google.com/file/d/1ZvLb...
Note that the FLAC audio track makes these video files incompatible with many devices/software, since putting FLAC audio inside a video container is not very standard.
