Detailscan both the decoded stream's DAC input and the "Line-In"
input be selected as on to mix the 2? be nice to listen to music + other things like voice/game noises/etc |
This task depends upon

I believe the Player can do this.
Or for Dj use.
I'll second this. After looking into the MAS datasheet it
seems possible to me, but I might have looked not thoroughly
enough.
It would be *very* helpfull, to have a configuration
possibility in e.g. F1/Sound Settings; maybe 'Line-In
Volume'? With this, one could plug a second archos and mix
them by their volumes or plug a PDA with speech output from
a navigation software.
All what would probably be necessary is to change the two
registers for the mixing volumes from default:
/* ADC scale 0%, DSP scale 100% */
mas_codec_writereg(6, 0x0000);
mas_codec_writereg(7, 0x4000);
to user selectable value(s):
0x0000 off
0x2000 50% (6 dB gain)
0x4000 100% (0 dB gain)
0x7F00 200% (+6 dB gain)
To make the decoder volume changeable too, might even help
for badly scaled mp3 files.
Unfortunately, I've got no working compiler setup to try it
and the ajbrec.ajz is not plain binary, otherwise I just
would have patched it :-)
Thank you!
