After troubleshooting configuration problems with several users, I believe I
have fixed the problem with the configure script that prevented some people from
building freqtweak. Anyone who had problems should definitely try the new
release.
Along with that, you get a 4096 freq bin mode, and a few tiny bugfixes.
http://freqtweak.sourceforge.net/
I added a short example of how to pipe alsaplayer through freqtweak and out your
speakers without messing with JACK patchbays (see Usage Tips section).

OK, here is a patch to fix that... new sourceforge file release is on its
way soon.

Hi all,
I have a Hoontech digital XG and a C-Media CMI (onboard) soundcard in my
machine. The external midi is now connected to the Hoontech digital XG
(ymfpci driver) and accessible by /dev/snd/midiC1D0. The hoontech card
also has a internal midi synth, but I can't find how to activate it. Does
anyone know how to do so? Do I need a new module? a different device? some
control program?
thanks,
Olivier
Hi,
>From the JACK FAQ:
"aRts, a streaming media architecture: aRts was not designed from the ground
up with low-latency in mind. Not a fault, but a design decision. A jack
output element could be written for aRts, though, as far as I can tell."
Anybody tried this already? If not, I would like to spend some time creating
an aRts output element, because my laptop soundchip doesn't have decent ALSA
drivers. And it seems easier to write a jack output for aRts than to debug
the es18xx ALSA drivers.

Announcing the initial release of FreqTweak (v0.4)
http://freqtweak.sourceforge.net
FreqTweak is a tool for FFT-based realtime audio spectral manipulation
and display. It provides several algorithms for processing audio data
in the frequency domain and a highly interactive GUI to manipulate the
associated filters for each. It also provides high-resolution spectral
displays in the form of scrolling- raster spectragrams and energy vs
frequency plots displaying both pre- and post-processed spectra.
It currently relies on JACK for low latency audio interconnection and
delivery. Thus, it is only supported on Linux.
FreqTweak is an extremely addictive audio toy, I have to pry myself
away from playing with it so I can work on it! I hope it has value
for serious audio work too (sound design, etc). The spectrum analysis
is pretty useful in its own right.
FreqTweak supports manipulating the spectral filters at several
frequency resolutions (64,128,256,512,1024, or 2048 bands) depending
on your needs and resources. Overlap and windowing are also
selectable.
The GUI filter graph manipulators (and analysis plots) have selectable
frequency scale types: 1x and 2x linear, and two log scales to help
with modulating the musical frequencies. Filters can be linked across
multiple channels. The plots are resizable and zoomable (y-axis) to
allow precise editing of filter values.
The current processing filters are described below in the order audio
is processed in the chain. Any or all of the filters can be
bypassed. The state of all filters can be stored or loaded as presets.
Spectral Analysis -- Multicolor scrolling-raster spectragram,
or energy vs. freq line or bar plots... one shows
pre-processed, another shows post-processed.
EQ -- Your basic multi-band frequency attenuation. But you get
an unhealthy number of bands...
Pitch Scaling -- This is an interesting application of
Sprengler's pitch scaling algorithm (used in Steve Harris'
LADSPA plugin). If you keep all the bins at the same scale, it
is equivalent to Steve's plugin, but when you start applying
different scales per frequency bin, things quickly get weird.
Gate -- This is a double filter where a given frequency band is
allowed to pass through (unaltered) if the power on that band
is between two dB thresholds... otherwise its gain is clamped
to 0.
Delay -- This lets you delay the audio on a per frequency-bin
basis yielding some pretty wild effects (or subtle, if you are
careful). A feedback filter controls the feedback of the delay
per bin (be careful with this one). This is basically what
Native Instrument's Spektral-Delay accomplishes. Granted, I
don't have all the automated filter modulations (yet ;). See
their website for audio examples of what is possible with this
cool effect.
Have fun... report bugs...

You said *exactly* what I (originally) wanted to say about
fvwm2. It's just that I have only used kde and fvwm2 and
wasn't sure what the others were like. But yes... loads
fast as %&*# and used (if my memory serves me well)
1 or 2 megs of ram.
Am I mistaken about the 1 or 2 megs of ram part?

Hello
I've just got my powerbook back after it took 3 weeks to replace the screen. The repair shop was kind enough to blow away my hard drive and install macos 9.1 so i'm now rebuilding my linux system. I've gone for yellow dog 2.3 (after the debian installer gave me too much gip).
Preamble over, heres the griff:
I've got kernel version 2.4.19-4a
i'm running alsa 0.9rc2 / snd-powermac (rc3 wouldn't build the powermac driver)
Some apps work fine, e.g.
xmms playing an mp3 (oss emulation)
pd 0.35 (native alsa)
Others have a very distorted sound unless the software volume level is very low, e.g.
audacity (oss emu)
SpiralSynthModular (oss emu)
1. has anyone else using ppc noticed this phenomenon of some apps being fine and others being very distorted?
2. does anyone have a good solution?
i had the same problem with my previous install on this machine when i had alsa/ benh2.4.19 kernel. the solution i found was to use the 2.4.10 yellow dog kernel + oss native module when running these audio apps. unfortunately this did not allow me to use alsa.
cheers

When I first started out using Linux, I used fvwm2. It used very little resources and booted up very quickly. I still have it on the SuSE 6.4 install, so it may still be out there somewhere.

A technical but mostly non-linux friend was asking me about where Ogg
Vorbis is relative to MP3's, given the current status of MP3 encoding
software.
I did a quick test of making an ogg from a wav, and my naive version
produced:
[lconrad@tuba renfaire]$ ls -l hercules*
-rw-rw-r-- 1 lconrad lconrad 4526080 Aug 18 14:14 hercules2.mp3
-rw-rw-r-- 1 lconrad lconrad 12220015 Sep 3 12:30 hercules2.ogg
-rw-rw-r-- 1 lconrad lconrad 49956104 Aug 18 14:09 hercules2.wav
I used ecasound to do the encoding, but what my ecasoundrc says it did
is:
ext-ogg-output-cmd = oggenc --raw -o %f
oggenc is:
[lconrad@tuba renfaire]$ oggenc -v
OggEnc v0.8 (libvorbis rc2)
So my question is, is there a way to get the ogg file down closer to
the size of the mp3 file?
