Example code in C for sound recording

    Hi,

    for the program I want to write I need to record sound
    and process it while recording.

    - AHIRecord works great but there is no C source code
    provided.

    - HDRecord from AHI developer package does not seem
    to work on my PegasosII and it also has m68k assembler
    source which I want to avoid (want to code pure
    C if possible)

    - RecordTest.c from AHI developer package does not
    seem to work when compilig with
    gcc -noixemul -o recordtest recordtest.c
    (even not after removing the __far stuff before
    buffer1[] and buffer2[] definition. I included
    some debug printfs with Delay(200) after each
    printf and I saw, that everything seems to work
    until the DoIO() call. When doing that call my
    PegasosII freezes completely (even the mouse
    pointer does not move anymore).

    Do you have a hint on how to change RecordTest.c to
    get it working with soundinput (I have connected
    a microphone to a preamplifier and the preamplifier
    to the line in port of my peg; this setup works
    if used with AHIRecord and with that prog I was
    able to record).

    Or do you know some other (small) C example code
    that shows how to read sound data from line in?

    (and btw.: any idea why mic in does not work and
    why I cannot set it active in PegasosMixer?)

    Thanks in advance and best regards

    I'm pretty sure you'd have more chance getting an answer on MorphOS Developer Connection, especially if you register.

    Also, did you check the AHI home page? There's a developer section.

    Hope it helps!

    Thanks for the hint, I will repost it on MorphOS
    Developer Connection then.

    I have the source directly from the AHI homepage but maybe I did some error during compilation...

    Best regards, ciao
