Have you upgraded or downgraded jack_capture and/or libsndfile since then? Which version of jack_capture are you currently using? Have you tried a different format than wavex? (wav is probably the the safest format to try since it's one that has been the most tested. Wav files has a 2gb limitation though, but jack_capture automatically writes to a new file whenever it reaches that limit.) There was a problem many years ago that I used (by accident) a 32 bit integer instead of 64 bit integer. Perhaps you are using one of those quite old versions of jack_capture.

Long-running jack_capture multi-track recording corruption?

by Andrew Grathwohl

Hi list, I am using jack_capture to record 2 inputs and 20 outputs going through SuperCollider for a duration of between 30-45 minutes, using the following command line: jack_capture -f wavex -p supernova:* test.wav This has worked well for my use case for several years. However, since yesterday this command line fails to capture the entire recorded performance, despite jack_capture showing the meters responding to the audio correctly. Whenever the recording duration exceeds approximately 20 minutes, the output file will only contain the first 5-10 minutes. However, if we only do a 5-10 minute recording, the entire recording is captured and saved properly. Seeking any insights about how to diagnose/fix these problems. Anyone here know where I ought to start? Thanks much, Andrew

Four free SFZ sample libraries

by Jeanette C.

Hey hey, I have just uploaded four sample libraries that I created with AutoSampler and DrumSampler: http://juliencoder.de/sound/index.html They are: Prophet Guitar: a guitar/clav like patch on the hybrid analogue/digital DSI/Sequential Prophet 12 (part of my Jeanny's Genius soundsets). Brute Bass: a solid bass patch on the analogue semi-modular Arturia MiniBrute 2s. Coast Bass: a gnarly, woddy "plucked" bass patch on the west/east coast semi-modular Make Noise 0-Coast. RD8 Kit 1: one drum kit (no congas) on the analogue Behringer RD-8 (Roaldn TR-808 clone), solid, but conservative, so no overlong boomy kick :) ). Hope someone can have some fun with them.

AutoSampler version 3: two new samplers

by Jeanette C.

Hey hey, AutoSampler version 3.0 is here (and will probably be the last, except for possible bugfixes): http://juliencoder.de/sound/autosampler-3.0.zip (Tested with Csound 6.15, might run with 6.14). There is one autosampler which can pause after a specified number of notes, so you can retune your old analogue synth. You can interactively choose a reference note, byt playing notes on a connected keyboard. A reference tone will be played from within the program. The next sampler is really new: Drum Sampler is specially designed to work with drum machines. It starts in play/exploration mode, where you can tweak sounds and listen. Then in record mode all played notes/sounds/trigger-buttons will be recorded. You can specify MIDI notes for hihats, they will be put into a mute group for the SFZ. SFZ files are created at the end. Round robins will automatically be detected. Play a note as often as you like. Files are named based on the MIDI note. You can simply rename them. I have recorded a sample set with each sampler, if anyone's interested, I can upload them. Good sampling and best wishes, Jeanette -- * Website: http://juliencoder.de - for summer is a state of sound * Youtube: https://www.youtube.com/channel/UCMS4rfGrTwz8W7jhC1Jnv7g * Audiobombs: https://www.audiobombs.com/users/jeanette_c * GitHub: https://github.com/jeanette-c Baby, take the time to realize I'm not the kind to sacrifice <3 (Britney Spears)

Released a small auto sampler

by Jeanette C.

Hey hey, I have released a small autosampler, implemented in Csound. It's easy enough to set up. http://juliencoder.de/sound/autosampler.csd Documentation for non-Csound users is at the top and again at the bottom. The autosampler support velocity layers, round robins, overall note range, note intervals, both mono and stereo sampling. The sampler will wait for a note to decay, but does not (yet) produce key release samples. Output files are named: chosen_name-MIDI_note_number-velcity-round_robin_index.wav I hope someone finds a use for it. :) Best wishes, Jeanette -- * Website: http://juliencoder.de - for summer is a state of sound * Youtube: https://www.youtube.com/channel/UCMS4rfGrTwz8W7jhC1Jnv7g * Audiobombs: https://www.audiobombs.com/users/jeanette_c * GitHub: https://github.com/jeanette-c All I need is time A moment that is mine While I'm in between <3 (Britney Spears)

[music] Water Colour Sky (abstract, downtempo electro)

by Jeanette C.

Hey hey, my latest song: https://youtu.be/3Pz44DnX5fQ Direct OGG: https://www.dropbox.com/s/y6s7uhibit0juz1/water_colour_sky.ogg A relaxed, relaxing deep downtempo electro piece, greatly inspired by "All My Love" by Rod Morris. It involved a lot of Csound for drums and shimmering effects, exploring FFT based synthesis, Karplus-Strong, granular synthesis and wavetables plus subtractive processing. It also features Yoshimi, LinuxSampler, setBfree and some analogue hardware. I hope you enjoy it and have a relaxing, lovely Sunday, Jeanette -- * Website: http://juliencoder.de - for summer is a state of sound * Youtube: https://www.youtube.com/channel/UCMS4rfGrTwz8W7jhC1Jnv7g * Audiobombs: https://www.audiobombs.com/users/jeanette_c * GitHub: https://github.com/jeanette-c Say hello to the girl that I am! <3 (Britney Spears)

Re: [LAU] qsampler isn't compiling from tar source

I was sent a personal e-mail advising me to install qttools5-dev-tools. This included /usr/lib/qt5/bin/lupdate. After doing so, the source code compiled and installed without error. As I mentioned, I was missing something obvious. Still, unless you know it, you don't know it.... Tom

qsampler isn't compiling from tar source

by tom haddington

Hello, List-- Actually, qsampler configures without errors. Running make returns no errors, either. When I run sudo make install, I get this error: lupdate: could not exec '/usr/lib/qt5/bin/lupdate': No such file or directory make: *** [Makefile:97: translations_lupdate] Error 1 I don't know much about coding, but took a look at the Makefile, which contains this line: export LUPDATE=/usr/bin/lupdate I tried putting lupdate in /usr/bin/qt5/bin, but that only made my terminal hang. I'm compiling on Ubuntu Studio 20.04. I'm sure I've missed something obvious. All help is appreciated. Take care! Tom

[music] Welcome to Neptune (3d binaural soundscape/scene)

by Jeanette C.

Hey hey, I have just released this piece (best listened to on headphones): https://youtu.be/U6GKSp1_vT8 It's a virtual journey from free space through the layers of Neptune's atmosphere down to the planet's core. All sounds are synthesized, but based on audio recordings from NASA's Voyager II when it had passed the planet. These would be audio representations of different instruments aboard the space probe. The text is an impression or short fragment that I had written down on some journey, not to Neptune though. :) The image is also synthesized, though not with Csound but with POV-Ray. Feedback is welcome, I hope you enjoy it.

Zoom H5 jack_iodelay

by Lorenzo Sutton

Hi David, all, Creating a new thread as the old one was pretty long... On 19/03/2021 15:22, David Kastrup wrote: [...] >> - Zoom H5 shows 4 inputs in jack: the L/R mics and the inputs 1 and 2 > > Oh, can you just put the headphones right next to the mics (makes > astonishingly little difference in comparison to direct connections) and > use jack_iodelay for measuring out the latency of the H5 with your > settings? > > Numbers are surprisingly hard to come by for any audio interface. > This is what I got by connecting jack_delay to one output and putting the headphone right in front of the microphones (connected only one to the jack_delay input). These are common jack settings I use or have used with this device, although the 32 Frames is very unstable and the 64 Frames one gets a few xruns depending on what it's used with (but still more usable). The 128 Frames settings is very stable. SR Fr/p Avg. delay reported (ms) ------+-------+------------------------- 48000 128,2 22.7 64,3 18.7 32,3 14.2 44100 128,2 25.2 64,3 20.6 96000 128,2 22.6 64,3 18.6 88200 64,3 18.6 Hope this is useful /interesting Lorenzo.
