Audio Compression Comparison

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. 0:00 - 32 kb/s MP3 0:10 - 32 kb/s WMA 0:20 - 32 kb/s AAC 0:30 - 32 kb/s Opus 0:40 - 64 kb/s MP3 0:50 - 64 kb/s WMA 1:00 - 64 kb/s Vorbis 1:10 - 64 kb/s AAC 1:20 - 64 kb/s Opus 1:30 - 96 kb/s MP3 1:40 - 96 kb/s WMA 1:50 - 96 kb/s Vorbis 2:00 - 96 kb/s AAC 2:10 - 96 kb/s Opus 2:20 - 128 kb/s MP3 2:30 - 128 kb/s WMA 2:40 - 128 kb/s WMA 2:50 - 128 kb/s AAC 3:00 - 128 kb/s Opus 3:10 - FLAC 24-bit, 44.1 kHz 3:20 - FLAC 24-bit, 22.05 kHz 3:30 - FLAC 24-bit, 11.025 kHz 3:40 - WAV 8-bit, 44.1 kHz Download audio samples (also includes MP2 and AC-3 which aren't included in the video): https://drive.google.com/drive/folders/1R2H6Q6kEh8OFctexkveVw2fk8QaNPu04?usp=sharing Download video with FLAC audio (to bypass YouTube audio compression): 4K60 (MP4 container): https://drive.google.com/file/d/1HEbxX7u5J2zd_FPAqSliU_RDrgKwi444/view?usp=sharing 4K60 (MKV container): https://drive.google.com/file/d/1sF0CXeNQ0yaxmRGctYean6gaVI9nLxw8/view?usp=sharing 720p30 (MP4 container): https://drive.google.com/file/d/1DTs50UBFuS1SD9bby2-ppFY0qH0IKI8e/view?usp=sharing 720p30 (MKV container): https://drive.google.com/file/d/1ZvLbeIO7vV_o4slldukrRkszqU6g2yGk/view?usp=sharing 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.
