Hello.
What tool is good at concatenating wav audio files?
Preferable command line ones.
Regards.

New subject: [linux-audio-user] No Sound from Laptop Speakers
Hello,
Just got a new company laptop (Gateway M675) and decided to install Linux
to it. I got just about of the built in hardware working under linux
(wifi, network, flash reader, etc) but can't get the sound to work just
right yet. I'm running Fedora Core 2 test 1 with a custom 2.6.3 kernel
(non Fedora Core). The laptop has an Intel Corp. 82801EB/ER (ICH5/ICH5R)
AC'97 Audio Controller (rev 02) sound card and I am using the Alsa
intel8x0 driver which loads correctly.
Now before some says to check the mixer and un-mute stuff, this has
already been done. Right now when I play a wav file, instead of the sound
coming out of the built in speakers its playing though the Mic jack (with
headphones plugged in). I've done a lot of searching and the only thing
I've found that might fix this problem is to reconfigure the output jacks
in Alsa but the post I saw this in did not say how this was done and I
can't seem to find any information in the Alsa documentation on how this
is done. I guess I would have to create a .asoundrc file but don't know
what needs to go in there to remap the the sound output to the laptop's
speakers instead of the Mic jack.
Any help on this will be much appreciated. Thanks for your time.

Sorry, its possibly you cant easily - in the worst case convert everything
to a RAW format, use cat, convert it back
sox foo.wav foo.raw
sox bar.wav bar.raw
cat foo.raw bar.raw > baz.raw
sox [some options] baz.raw baz.wav
ecasound would be better :)

I agree with Steve. There's plenty of ways to aid in what you're trying
to do (depending how complex you want to be). If you're just trying to
"glue" fileA.wav to the end of fileB.wav, the you can use "ecalength"
to
find the length of fileA.wav....
[bash] ecalength fileA.wav
--> 213.542 (seconds)
then do...
ecasound -i:fileA.wav -t:213.542 -o:fileB.wav -y:213.542
I've tried this, but haven't really listened for accuracy.
From the ecasound man page...
-t:seconds
Sets processing time in seconds (doesn't have to be an integer value).
If processing time isn't set, engine stops when all inputs are finished.
-y:seconds
Sets starting position for last specified input/output.
For more advanced "splicing" of files into other files, you can use
ecasound in "interactive mode" (ecasound -c) to be able to do simple
commands. Ultimatly, you could obtain position markers....
ecasound -c -i:fileA.wav -o:/dev/dsp
ecasound ('h' for help)> t
(Start playing fileA.wav)
ecasound ('h' for help)> getpos
(return the current position of fileA.wav)

Actually you would find the length of fileB.wav...
[bash] ecalength fileB.wav
--> fileB.wav: 240.658s (4m1s)
Then do...
ecasound -i:fileA.wav -o:fileB.wav -y:240.658
I just downloaded and compiled "sndfile-concat" and it's much easier. It
will even glue files of different types and bit rates without having to
convert them first (but not files with different number of channels).

You might want to use ecasound for "splicing" differnt files into other
files. Of course, it's also an (complete) multitracker, effect processor
(and much more actually).

A small C program using libsndfile:
http://www.mega-nerd.com/libsndfile/sndfile-concat.c
Its coand line and does a lot more than just WAV files. Its
also smart enough to concat files with different data formats
(ie if file one is 16 bit PCM and file 2 is 24 bit PCM, the
output file will be the same format as the first input file).
HTH,
Erik
