I am still investigating but I believe The answer may be in the
jam20170510.ecs file. I'm not sure exactly how to interpret what it is
telling us though, so I am passing it on and will do more playing
later.

Kirk,
I have frequency set to 48000 and if I use the 'file' command on
nama/jam-2017-05-10/.wav/jam_1.wav it does in fact show 16 bit
little-endian 48000hz. Still, it plays slow inside nama. If I play the
jam_1.wav file with aplay or mplayer it sounds fine but inside nama
it's slow.
Fortunately, we have reliable ways to diagnose what is
happening. cs-save-as /home/kirk/jam20170510.ecs
I would inspect this file. Please post it to the list.
Probably next, I would get rid of the files in nama/jam-2017-05-10/.wav
in case they were wrongly resampled.
Then, I would, recopy in the audio file (or just use a symlink )
cd nama/jam-2017-05-10/.wav/
ln -s /home/kirk/jam-2017-05-10.wav jam.wav
Then repeat listening test. You can also test ecasound
outside of Nama.
ecasound -f:16,1,48000 -i testfile.wav -o alsa
Jeanette: I don't think doing a global find and replace in .namarc
will fix the problem because the only places where 44100 shows up is
in the settings for cd-mono and cd-stereo which are in the same
section as frequency.
cd-mono and cd-stereo are definitions, only. Possibly used
in the mixdown session of namarc. Actually, no, in default
namarc we have:
mix_to_disk_format: s16_le,N,frequency,i
You might set it to cd-stereo, if you want to burn a CD,
I've looked at the state.json file in the nama/jam-2017-05-10
directory but don't see anything suspicious. I think for completeness
I'll include the .namarc and state.json files you recommended I pass
along, though I don't think the problem is there.
Chain setup file Setup.ecs from the project directory is
also useful. It is the configuration file we use to setup
ecasound. It's what the 'chains' command lists.
This is one of the first places we learn to look.
the cs-save-as command is actually at the ecasound
level, and dumps the state of the ecasound engine.
Similar to the 'chains' output.
Hope this helps :)
Joel
If the jam_1.wav file wasn't so bloody large I'd send it along as well
but it's slightly over 1.1Gb which is why I'm interested in slicing it
up into individual pieces to work with more conveniently.

Kirk,
Maybe it's a config file issue.
Generally people configure their system for a single sample
rate for all projects. For example, if you recorded your
.wav files at 48kHz, then you set that in your namarc file.
We set it by defining 'frequency'
in the abbreviations section .
sample_rate: frequency # leave this line alone
abbreviations:
frequency: 48000
I would produce your work at that frequency. No need to
mixdown to 44100 unless you're burning a CD?
If you 'frequency' and 'sample_rate' set with different
values, you could definitely some unexpected behavior.
Less than awesome as that could trip you up.
Also, it's useful to have some utility that prints
diagnostics on media files, such as 'ffprobe' or 'file'.
cheers,
Joel

Hello Joel et al: I aplogize for the delay in getting back on this
topic but after the last pull and compile things seemed to be working
okay. The thing is I had down sampled my jam-2017-05-10.wav file to
44khz before importing it. I decided to try blowing away the
jam-2017-05-10 subdirectory and start over with the original file and
it started resampling the 48khz to 44khz because I had changed the
frequency variable to 44100. Unfortunately my machine over heated and
crapped out before completing the resample so i decided to set the
frequency variable back to 48000 and pull it in without resampling. It
pulled it in no problem but still plays slower than what it should. I
tried changing the consumer input and output variables to sample_rate
to match the files frequency but that didn't seem to have any affect.
If you have any other ideas I'd like to hear them. I can always
resample things before importing them but the microphone I've ordered
which is class-compliant usb also records at 48khz so I'm not exactly
sure how to handle that when trying to record with nama.
The fading on start and stop seems to be working now and there are no
crunching that I can tell now. I did manage to lose my sound when
playing around extracting files but I probably told it to go do
something impossible, knowing me.
Thanks for all your help Joel and Jeanette.
Kirk
