Have you tried tweaking the alsa profiles and set Bass Filter to either 100Hz @ 8kHz (== 600Hz @ 48kHz) or 200Hz @ 8kHz (== 1200Hz @ 48kHz) and Bass Boost to 15? I find the quality just fine for eg. in-car music playing. Even when using headphones (Koss KSC-35) I find the quality acceptable, even though the color of the sound is not completely neutral. I tend to prefer 200Hz @ 8kHz, and probably the high-pass filter effect of the output on Neo is indeed quite high, though sometimes I wonder if the midrange is overemphasized with that setting still. I was planning to see about playing back a frequency sweep on Neo, but seemingly forgot about it. Anyway, I now put one 20Hz-20000Hz sweep file at http://users.tkk.fi/~tajyrink/moko/20-20k_60s.ogg (vorbis quality 8, should be good enough), if someone with proper(ish) recording equipment can record with eg. 100Hz @ 8kHz and 200Hz @ 8kHz settings with Bass Boost at some level like 15. I don't know what quality an average motherboard "HD" Audio recording is, but will try it anyway myself at some point with various settings to see what kind of slopes one gets. -Timo _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
