I wasn't quite following the '-t' discussion, but is this problem
a similar one to that were reported ("-t: at 48000", although this is
about a lower samplerate.)?

attached mail follows:

Package: ecasound2.2
Version: 2.2.3-1
Severity: normal

Despite the claim in /usr/share/doc/ecasound2.2/NEWS.gz that this has
supposedly been fixed in version 2.2.1, I encounter this misbehaviour:

    I use ecasound to record at a samplerate which is not the standard
44100 Hz. When using the option -t to stop recording after a given time, the
resulting length is completely wrong because ecasound seems to count samples
assuming the "standard" sample rate. For example, I use the following command
line:

        ecasound -d:3 -D -ev -evp -ezf -r -z:db -z:nointbuf \
            -f:s16_le,2,32000 -i:alsa -o stdout -t:$timeout

    If I'd like to have an output length of e.g. 300 seconds, I'd have to
calculate 300 * 32000 / 44100 and insert that as $timeout above to get the
correct length.

Thanks,

    - Stephan.
