Can any VLSI device do FLAC decoding and equalizer at the same time?
What about FLAC encoding and equalizer at the same time?

vs1053b can perform FLAC decoding with the vs1053b-patches package and perform Bass/Treble control at the same time.
vs1063a can perform FLAC decoding and use Bass/Treble control or 5-Band EQ at the same time.

There is an experimental FLAC encoder in the vs1063a Patches Package. EQ is not possible during encoding, not for the encoded audio, nor for the monitoring audio.

Thx for your reply. The 5-band EQ has fixed band-frequencies, correct?

thx

No, the frequencies are adjustable. See the vs1063a datasheet, 11.10.6.
