A friend of mine was telling me how he listens to his speech podcasts
on his iPod at faster than natural playback speeds. I'd like to do
this with an audio file player which can do the same on Linux. Which
one(s) should I investigate? Of course, I want the original pitch at
any playback speed.
Thanks....

Hello everyone, here's some new (as in new to the internet, the
mastering was finished before christmas...) music from me. Not done
completely in linux this time, actually pretty far from it:
Drums were recorded in a professional studio on Windows and Cubase,
along with any rhythm guitar we had time for that weekend after
drumming was done. We also did mixing and mastering here. Bass was
probably recorded in Windows too, but I was not involved in that.
Female vocals, accordion and acoustic guitars were recorded at my
father's Mac with Pro Tools. Simply because I had to borrow those
instruments from him, the vocalist is my sister, and I live in a
completely different city.
The rest was recorded at home on my linux box with Ardour.
It's a slow type of doom / rock / metal, mostly instrumental, trying
to evoke the many moods you can get in when you get homesick and are
far away from home. Check it out at http://hjemlengsel.bandcamp.com

Hello:
I am very much new to Linux and Linux audio. I am trying to measure audio
IO latency for my system.
Jdelay seems to be the right tool but when I run it on the terminal, I am
getting message "Signal below threshold..." which probably might be because
Jack is trying to capture audio and ends up getting the low noise floor
because I do not have meaningful signal source connected. But then I tried
to patch the this App to the qJACKctl app but the settings console is
not straight forward to interpret. as it involved many parameters.
I guess there are # of frames per period that may eventually be used
to calculate the target latency but *is there a step-by step document
description for Jdelay and any other JACK tools and also using JACK audio
server in an effective manner*? Also, qJACKctl console does not offer
options for very low sampling rates like 8 KHz. With ALSA, this should be
possible but may be this particular tool does not support it. Can anyone
help here?
Thanks,

Haven't been using Linux for sound recording for some 5 years now, so I
feel rather out-of-date. I used to use jackd, rosegarden, timemachine,
etc, but I left the music
behind and now into ham radio.
I have a fresh Kubuntu install (10.4) and I want to run Fldigi (which
reads line-in and does PCM out) and simultaneously record everything
that is being read-in and transmitted out. Fldigi is no jack
application and I can't find a workaround to make it like jack. I also
can't find out how to directly talk to my sound card (Ensoniq ENS1371).
It must be possible to share and route all the audio in my box, or not?
Anyone care to guide me back in and give me some pointers on where to
start? Greatly
appreciated.

I want to build a system that monitors several audio signals. It will
need to run:
alsa
jackd
meterbridge (3 stereo pairs)
alsaplayer
silentjack (3 instances)
There will be three soundcards.
Synchronicity and realtime are not important. Long-term stability (i.e.
running 24/7) is.
Silentjack will need to run scripts that send emails in the event of
prog failures
It will need to boot into a script that starts all the above.
It will not need a desktop - a straightforward windowmanager like fvwm
is sufficient.
It would be nice if it ran on elderly hardware - a PIII/733 with 512MB
is available.
I am expecting to modify meterbridge, so the existence of a binary
package is not important for that application. The others, however,
will be standard.
Any thoughts which distribution would be the best starting point?
Andrew.
Hi,
I'm trying to get two soundcards to work. One MOTU UltraLite with
FFADO and a USB Edirol PCR-1. No Luck with either.
What should I do to configure the Edirol? (Maybe the easier one?) The
core installation of planet-ccrma is enough? I tried to start up JACK
but the system does not recognize the soundcard. (Fedora 13 64-bit
with planet-ccrma).
Thanks!

For some reason, the driver has a quirk only for the MIDI interface of
the PCR-1 but not for the PCM interfaces.
Try adding the following entry to sound/usb/quirks-table.h or
usbquirks.h and then recompiling the driver:
{
USB_DEVICE(0x0582, 0x0064),
.driver_info = (unsigned long) & (const struct snd_usb_audio_quirk) {
.vendor_name = "EDIROL",
.product_name = "PCR-1",
.ifnum = QUIRK_ANY_INTERFACE,
.type = QUIRK_COMPOSITE,
.data = (const struct snd_usb_audio_quirk[]) {
{
.ifnum = 1,
.type = QUIRK_AUDIO_STANDARD_INTERFACE
},
{
.ifnum = 2,
.type = QUIRK_AUDIO_STANDARD_INTERFACE
},
{
.ifnum = -1
}
}
}
},

Thanks, Mike, but the /etc/modules solution works for me on Ubuntu.
Thanks to all for the help !

I wanted to draw everyone's attention to some plugins from linuxDSP,
which can be found here:
http://www.linuxdsp.co.uk
They are available as LV2 plugins compatible with most recent versions
of Ardour and Qtractor (and other hosts that support the required LV2
extensions) and also as linux VSTs for hosts such as energyXT, renoise
(and also Qtractor when built with the VST headers). They are also
available as standalone JACK client applications.
The most recent releases (the Pro-EQ and Pro-Dynamics) are specifically
intended to add professional quality channel processing to DAWs e.g.
Ardour, and in addition to high quality signal processing also feature
an innovative resizable GUI.
All the LV2 plugins have a GUI that will display the same way in a GTK
host as in a Qt host - which is not always the case with other plugins.
The plugins are not all free, but as one of the few full-time developers
of linux audio software (with over 20 years professional experience of
pro-audio), it is necessary to cover the cost of development and
provision of the software - and I think they are still very reasonably
priced.
Thanks.

Greetings,
I'm sure there's a quick & easy answer to my question, but I'm so thick
this morning I can't find it.
I want the snd-virmidi module to autoload when I boot my Ubuntu Lucid
box. I've already fixed its order, and when I load it from the prompt it
takes its proper place in my defined order of devices. But I'm tired of
loading it manually every session: How can I autoload it at boot time ?
TIA!
Waiting to discover the depths of my ignorance,
