I have a Lenovo X61 I bought second hand hoping to use it for some audio work. But when using a USB output device (a MobilePRE M-Audio through jackd) the volume is very low. Too low to drive my amplifiers or even my headphones. In exactly the same system I use an Acer laptop with no problems at all. I cannot find any mixer controls that help. Does anyone out there have a similar problem and know if it can be solved? Where I should start? cheers Worik -- Why is the legal status of chardonnay different to that of cannabis? root(a)worik.org 021-1680650, (03) 4821804 Aotearoa (New Zealand) I voted for love

[ANN] Summer'15 release frenzy wrap up!

by Rui Nuno Capela

Hello? Summer'15 release frenzy is not over yet!... well, it's only over on the 'equinox' anyway... * QmidiNet - A MIDI Network Gateway via UDP/IP Multicast * QmidiNet [1] 0.3.0 has been released! QmidiNet [1] is a MIDI network gateway application that sends and receives MIDI data (ALSA-MIDI and JACK-MIDI) over the network, using UDP/IP multicast. Inspired by multimidicast [4] and designed to be compatible with ipMIDI [5] for Windows. Website: http://qmidinet.sourceforge.net Project page: http://sourceforge.net/projects/qmidinet Downloads: http://sourceforge.net/projects/qmidinet/files - source tarball: http://download.sourceforge.net/qmidinet/qmidinet-0.3.0.tar.gz - source package: http://download.sourceforge.net/qmidinet/qmidinet-0.3.0-8.rncbc.suse132.src… - binary packages: http://download.sourceforge.net/qmidinet/qmidinet-0.3.0-8.rncbc.suse132.i58… http://download.sourceforge.net/qmidinet/qmidinet-0.3.0-8.rncbc.suse132.x86… Change-log: - System tray icon now blinks on network send/receive activity. - Prefer Qt5 over Qt4 by default with configure script. - Complete rewrite of Qt4 vs. Qt5 configure builds. - Fixed for some strict tests for Qt4 vs. Qt5 configure builds. * QmidiCtl - A MIDI Remote Controller via UDP/IP Multicast * QmidiCtl [2] 0.3.0 has been released! QmidiCtl [2] is a MIDI remote controller application that sends MIDI data over the network, using UDP/IP multicast. Inspired by multimidicast [4] and designed to be compatible with ipMIDI [5] for Windows. QmidiCtl [2] has been primarily designed for the Maemo [6] enabled handheld devices, namely the Nokia N900 [7] and also being promoted to the Maemo Package [8] repositories. Nevertheless, QmidiCtl may still be found effective as a regular desktop application as well.

Discovering file format

by Will Godfrey

I have about 150 uncompressed audio files that I want to properly categorise, relatively quickly. The very oldest were recorded as 16bit 44.1k, more recent ones were 16bit, 48k and the latest ones 24bit 48k. I've moved them all into the same directory, so is there a simple script I can run that will scan this and list the name and details of each file? I can find plenty of programs that can change the format, but can't find any that will just tell me what it is :( -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune. Exchange them and we can both have a poem, a tune, and a song.

Actually no... I want to test if the algorithm works equally well (at least in the reduced bandwidth given by the 8 kHz sampling) with respect to the 44.1 kHz sample rate case! That's becouse the target hardware has a low sample rate, but with a proper anti-aliasing filter. For now, I'm designing the algorithm on a PC with jack mainly for 2 reasons: 1- Debugging is far more simple 2- I don't have the target hardware yet :) > >> Maybe I've to put a ladspa low-pass near 4 kHz just after my signal >> source? > Of course you cannot output anything higher than the Nyquist frequency. > If your source is higher frequency than output and you need > downsampling, a brickwall low pass filter is necessary. Sure... I was thinking that jack 'dummy' driver takes care of resampling, but clearly that's not the case (as I mentioned before, I've never used the dummy driver before :) ) > > BTW why did you reply privately and not to the list?

Re: [LAU] Problem getting started with Midi editing - no sound!

by David Sumbler

Thanks for all your replies. I was on digest (I have now turned this off), so I didn't get most of the replies until this afternoon. I'm encouraged, because it seems that much of what I have been doing was correct - and discouraged, because I still haven't got any sound! Ralf's suggested running 'aplay -l'. On my desktop computer I get this output: > **** List of PLAYBACK Hardware Devices **** > card 0: Intel [HDA Intel], device 0: VT1708S Analog [VT1708S Analog] > Subdevices: 1/1 > Subdevice #0: subdevice #0 > card 0: Intel [HDA Intel], device 1: VT1708S Digital [VT1708S Digital] > Subdevices: 1/1 > Subdevice #0: subdevice #0 > card 0: Intel [HDA Intel], device 2: VT1708S HP [VT1708S HP] > Subdevices: 1/1 > Subdevice #0: subdevice #0 > card 1: Speaker [USB Speaker], device 0: USB Audio [USB Audio] > Subdevices: 1/1 > Subdevice #0: subdevice #0 > card 2: NVidia [HDA NVidia], device 3: HDMI 0 [HDMI 0] > Subdevices: 1/1 > Subdevice #0: subdevice #0 > card 2: NVidia [HDA NVidia], device 7: HDMI 0 [HDMI 0] > Subdevices: 1/1 > Subdevice #0: subdevice #0 > card 2: NVidia [HDA NVidia], device 8: HDMI 0 [HDMI 0] > Subdevices: 1/1 > Subdevice #0: subdevice #0 > card 2: NVidia [HDA NVidia], device 9: HDMI 0 [HDMI 0] > Subdevices: 1/1 > Subdevice #0: subdevice #0 I have 2 USB speakers connected to this computer. When I run 'card=0; killall -9 jackd; jackd -dalsa -dhw:$card -r48000 -p1024 -n2' for each of cards 0, 1 and 2, then open QjackCtl, Qsynth and Qtractor I typically get: > jackd: no process found > jackdmp 1.9.8 > Copyright 2001-2005 Paul Davis and others. > Copyright 2004-2011 Grame. > jackdmp comes with ABSOLUTELY NO WARRANTY > This is free software, and you are welcome to redistribute it > under certain conditions; see the file COPYING for details > JACK server starting in realtime mode with priority 10 > audio_reservation_init > Acquire audio card Audio0 > creating alsa driver ... hw:|hw:|1024|2|48000|0|0|nomon|swmeter|-|32bit > configuring for 48000Hz, period = 1024 frames (21.3 ms), buffer = 2 periods > ALSA: final selected sample format for capture: 32bit integer little-endian > ALSA: use 2 periods for capture > ALSA: final selected sample format for playback: 32bit integer little-endian > ALSA: use 2 periods for playback > JackEngine::XRun: client = Qtractor was not run: state = 1 > JackAudioDriver::ProcessGraphAsyncMaster: Process error > JackEngine::XRun: client = Qtractor was not run: state = 1 > JackAudioDriver::ProcessGraphAsyncMaster: Process error > JackAudioDriver::ProcessGraphAsyncMaster: Process error > JackEngine::XRun: client = Qtractor was not run: state = 1 > JackAudioDriver::ProcessGraphAsyncMaster: Process error > JackEngine::XRun: client = Qtractor was not run: state = 1 > JackAudioDriver::ProcessGraphAsyncMaster: Process error > JackAudioDriver::ProcessGraphAsyncMaster: Process error > JackEngine::XRun: client = Qtractor was not run: state = 1 Sometimes I get references to Qsynth rather than Qtractor, but never both. It doesn't seem to depend on which card I am using. Incidentally, the output always refers to audio card Audio0, even when $card is set to 1 or 2. rncbc's suggestions were helpful. I have FluidR3_GM.sf2 loaded in Qsynth, and I checked that the mid input driver and audio output driver were as suggested. The rest of the instructions confirmed that I was importing the midi file correctly and making appropriate connections in Qtractor. Thanks also to Bob, Will and Jeremy for suggestions. I haven't actually got the piano here, so I can't try connecting it at the moment, but in any case I want to make sure I can get sound from Qtractor or something similar first. David

Maybe the very beginning is to run in terminal killall pulseaudio and then follow the steps given by other people on the list HTH,Fred On Mon, 14 Sep 2015 20:42:24 +0100 David Sumbler <david(a)aeolia.co.uk> wrote: > I have hesitated for weeks to post here with such a basic and possibly > stupid problem, but I am at my wits end with this. > > I run Ubuntu 12.04 on a desktop computer and also on a small notebook. > Sound is fine on both of them, and I can play midi files through > tiMidity with no problem. > > I want to use a midi-capable electric piano as an input device, and I > reckoned the first thing to do was to get some suitable software and > make sure I could play a midi file from a midi editor. > > If anyone feels they have the patience to try to point me in the right > direction, I shall be very grateful indeed. > > David
