Effects Chains

Hi,
I'd like to do the following in one sox invocation, and I'm not sure if this
needs multiple effects chains or not:
1) Change the sample rate of my file
2) Trim a specified number of samples from the front and back (sample count
is at the new sample rate)
3) Zero out the audio at several locations (position should be relative to
the beginning of the resulting resampled and trimmed audio)
4) Write the result to a file

Is this command ok or do I need to use multiple effects chains for this?:
sox $infile $outfile speed $speed_factor rate -v trim "$chopFrontSamples"s
"$chopLengthSamples"s pad "$length1"s <at> "$position1"s
"$length2"s <at> "$position2"s 

Thanks
Alex

Wow! That's a pretty neat trick!  *smile*

What command did you use?

Are you wanting to mix the two originals to create the third?
Or are you wanting to concatenate them (connect them end to end)?

You could run "soxi first.wav second.wav third.wav" and let us
know the length, channel count, bit depth, and sample rate
of each of them.

If you are wanting first.wav and second.wav to be connected end
to end in the file third.wav the size is pretty close to just
adding the two sizes together.

Oh, also, what does the third one sound like? Is it functionally
and sonically correct, just too large?

Re: How to reduce the size after combine a few wav files

Philip:

I just want to do the simple concatenation, 2-4 files to one.
The big file generated sounds OK, a little off from two originals,
acceptable sound, but too lager the size.

I tried your new command soxi as following:
soxi t1.wav t2.wav t3.wav

The command displays following:
Input File      : 't1.wav'
Channels        :  1
Sample Rate     :  8000
Precision       : 16-bit
Duration        : 00:02:35.52 = 1244160 samples ~ 11664 CDDA sectors
Sample Encoding : GSM

Input File      : 't2.wav'
Channels        :  1
Sample Rate     :  8000
Precision       : 16-bit
Duration        : 00:02:08.20 = 1025600 samples ~ 9615 CDDA sectors
Sample Encoding : GSM

soxi formats: can't open input file 't3.wav': No such file or directory

Thanks,

James

James, we now have the information about your two source files... but
what about the resulting files that combines them both?

Re: How to reduce the size after combine a few wav files

My problem is resolved.
Thanks Philip's soxi information.
I read the sox document, add -g option into command line as:
sox t1.wav t2.wav -g t3.wav

The size of new generated file is 451K, it is exactly the sum
of two original files.

I really appreciate the help.

James

It looks okay to me -- give it a try...

Only thing I would add is that pad doesn't zero-out samples (i.e. a 'mute' function) it inserts silence;
hope that's what you need.

Ah, but this is a bug: the -g should be implied in this case.
Fixed in CVS.
