    Hi,

    I want to split an audio file containing crow calls at points
    where no crow call is. The "silence" in between is not exactly
    "silence" but some low level noise.

[snipped]

    However, there is `mp3splt`, provided in the package 
`media-sound/mp3splt`.
    It's described in the question provided as a comment to your UNIX 
S.E.\ link.

    mp3splt primarily works with mp3s, but can also support ogg, which 
can be a
    container format for flac. I've never used it myself, but it looks 
promising,
    providing you are OK with placing your flacs inside an ogg.

The package media-sound/mp3splt has use flag "flac". If set mp3splt can 
directly read and write flac files.

I have used mp3splt to successfully split podcast files for burning to a 
CD. It has many options that allow tuning of the split points. I found 
it a pain to setup, but now that setup in complete it works reliably.

Hi Tom,

thanks for the info! :)

In the meanwhile I have used Audacity...it has a "Sound finder" and
"Silence finder" tool under the "Analyse Tab", which has some very
handy parameters.

The result will be visualised before any split file is written and can
be manually corrected per segment and to each segment can be listened separately 
beforhand.

Cheers!
