[Profiling][FFT][AArch64] FFT Profiling data on AArch64
Hi everyone,
I have profiled Opus on AArch64. I just run opus_demo with some pcm files.
Following is time proportion of FFT with different bitrate.
Bitrate | Time cost by FFT/iFFT
24kb/s | 15%
48kb/s | 15%
96kb/s | 13%
Any comment? I want some data close to real application, any suggestion?
Thanks,
Phil Wang

Potential transient pre-echo reduction filter
Hey everyone.
I've been designing my own audio codec with extremely strict
decode-performance constraints (including a fixed block size), which led
me to attempting a number of unorthodox things to squeeze as much
quality as possible.
One surprising thing I discovered just earlier today was an extremely
cheap method of reducing pre-echo during transients, without using short
blocks (and
