I'd like to use a T4.1 with a 32/64/128 mbyte spi flash for polyphonic audio playback (10+ streams possible?)
The streams are mono 16-bit 24kHz (or similar mid-quality). Processing will probably be limited to gain and short delay for spatial positioning of the mono streams in the stereo output.
I'm seeing different supported spi flash chips on the Audio Lib page and on the T4.1 flash expansion page. Maybe this is because of differences between the Audio Adapter spi interface and the T4.1 quad bit i/o? I've also seen discussion of larger chips in discussion threads, but I'm not sure if these are officially supported.
My application does not use PSRAM.
I would like to use the spi flash pads on the back of the T4.1 with quad i/o and high clock speeds. Can the Audio Lib 'playFlashRaw' play files off the T4.1 serial flash?
Can anyone recommend specific 128/64/32 MB chips that are known to work well on the T4.1 with the Audio library in this way? Larger is better, but not more than 128MB. Preferably in-stock at digikey or mouser.
Thanks!
