Reply to comment by Jackattack736 in Holy shit is “Tom’s Diner” by Suzanne Vega & DNA so godamn good. by treeillusion

It’s a great song for testing.

One of the things that makes the MP3 format good at compression is its ability to dynamically shift data between time and frequency. It can decide on the fly, at any given point in time, whether it wants to give more emphasis to percussion and transients or whether it wants to give more data to whistles and tones.

Tom’s Diner was probably chosen because it contains a good blended mix of sharp transients and long tones.

But is that in the case of VARIABLE Bit-Rate, or CONSTANT Bit-Rate???

Is VBR ~superior~ to CBR???

Have I been going about this all wrong the whole time????

I always thought a Constant Bitrate was more consistent.

Also, how do you feel about ATRAC?

Just use Opus. It’s superior to everything else.

Yeah, Opus has a lot of neat little tricks under the hood that make it really good at sound compression, for both music and human voice. And it’s also open source! Youtube, Discord and Whatsapp all use it as their primary audio codec as far as I know, with youtube using it as part of the .ogg container.
