thanks for your response! Sorry for writing just a private e-mail to
you, but so far I haven't been subscribed to the list. I just read the
discussions via the Rockbox web site...
Well, now I am subscribed and this is my first post...
So hello to everybody!! :-)
As I've written above, I am really interested in a WAV / PCM codec for
the Archos version of Rockbox, especially for being able to do high
In normal MP3 recordings (even using the highest quality settings)
frequencies above about 15.500 Hz are simply cut off. With WAV
recordings, it should be possible to record up to 22.100 or 24.000 Hz
(using sampling rates of 44.100 or 48.000 Hz respectively.)
Thanks to [IDC]Dragon's efforts, the PCM codec firmware and
documentation is readily available in the Data sheets section, but
unfortunately it has not been implemented into Rockbox yet. Please
correct me if I'm wrong...
I've read on the discussions that Amiconn and Oxygen77 spent some time
on the WAV codec, but I don't know if they had some success and if they
are still working on this issue.
So I'd like to appeal to the devs to keep on working on the WAV codec.
It would be a great improvement for the recording quality of the Jukebox
Recorder and also a great addition to the other Jukeboxes, as Bluechip
has already written above (play WAV and MOD files, do track mixing and
other fancy things.)
To everyone on the mailing list: Please join this discussion if you are
interested in either WAV playback or WAV recording, so that Bluechip and
the other Rockbox devs are encouraged to spend some time on implementing
the codec! If someone already had some success with implementing it,
please drop a line!
