JAPA(1) General Commands Manual JAPA(1)NAME
japa - jack or alsa perceptual analyser
SYNOPSIS
japa {-h|-A|-J} [options]
DESCRIPTION
Japa (JACK and ALSA Perceptual Analyser), is a 'perceptual' or 'psychoacoustic' audio spectrum analyser. Possible uses include spectrum
monitoring while mixing or mastering, evaluation of ambient noise, and (using pink noise), equalisation of PA systems. For more information
see /usr/share/doc/japa/README.gz.
OPTIONS
One out of -A and -J must be given.
-h Show summary of options.
-J Use jack.
-A Use alsa.
-d <device>
If using alsa: Specify alsa device. Defaults to hw:0.0.
-r <rate>
If using alsa: Specify sample frequency. Defaults to 48000.
-p <period>
If using alsa: Specify period size. Defaults to 1024.
-n <nfrags>
If using alsa: Specify number of fragments. Defaults to 2.

jconv - is a Convolution Engine for JACK using FFT-based partitioned convolution with multiple partition sizes.
SYNOPSIS
jconv [options][config-file][connect-file]
DESCRIPTION
This manual page documents briefly the jconv program.
jconv is a Convolution Engine for JACK, based on FFT convolution using the convolution engine for reverberation processing. This distrib-
utes the calculation over up to five threads, one for each partition size, running at priorities just below the the one of JACK's process-
ing thread.
To run this program you need config file and wav file for convolution. Demo config files you can find in /usr/share/jack-jconv/config-files
directory.
(You have to edit path to your convolution wav file)
Set of wav files you can download from Fons Adriaensen's web pages http://www.kokkinizita.net/linuxaudio/downloads/index.html (jconv-
reverbs.tar.bz2) or you can use another convolution files which are supported by libsndfile.
Some other info can be found in README and README.COFNFIG files in /usr/share/doc/jack-jconv.
OPTIONS
A summary of options is included below.
-h Display short help
-v Print partition list to stdout [off]
-L <nframes>
Try to compensate <nframes> latency
-M Use the FFTW_MEASURE option [off]
-N <name>
Name to use as JACK client [jconv]

Hi:
The OS is Slackware 14.0. When, after 14.0 install I first ran alsamixer, I got an error message and it quit. After some googling, I created /etc/modprobe.d/alsa.conf with these lines:
alias snd-card-0 snd_hda_intel
alias sound-slot-0 snd_hda_intel
options snd_hda_intel... (0 Replies)

Well guys, this MUST be a first.
This is DEMO code only and has NO error detection or correction, nor out of bounds checking.
I have succumbed to Python and scipy to do the FFT heavy lifting as I have absolutely no idea where to start do such a thing using AWK. This is a taster for me to... (7 Replies)
