Subject: Re: [nama] Still not quite right
Date: Tue, 22 Aug 2017 06:55:33 -0400 (EDT)
Hi Joel: Thanks for the quick response. I was just trying to find what
worked with my playing around and set the original values back after
each test.
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.
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.
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.
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
