I tried to hardcodes parameters in a2play - I can tweak them but I
don't get good results.

If I had a pocket PC running windows, yes. Since I only have a Zaurus
and a Simpad running Windows CE.NET, it won't be possible
immediately. The worst is I don't have the drivers CD.

I thought I had posted that ?
a2play reports:
subbands =3D 1
allocation method =3D 1
channel_mode =3D 2
blocks =3D 3
sampling frequency =3D 2
bitpool =3D 32
frame len =3D 72

That's when it works better (the only problem is the audio being 2 to
4 times faster than it should be- it's hard to tell.)

Before I tried rcplay, when it was skipping a lot, I had a2play reporting=
:
subbands =3D 0
allocation method =3D 1
channel_mode =3D 0
blocks =3D 3
sampling frequency =3D 3
bitpool =3D 18
frame len =3D 38

Will do.
