There are lots of guitar to USB audio devices out there and it seems they have all done them wrong. I modified one of them and it actually sounds very good. Perhaps better than plugging into the "high impedance" input of many audio interfaces or using a DI box into a mic input. The result is a much more open sound in particular with single coil pickups (or tapped as I happen to have). Why do I think they have likely all done them wrong? The Application notes say: "Please follow the reference schematic for microphone section design." So not only is it easy but it is recomended. I am sure it works well for a computer mic. Anyway, for those who want a good quility direct to usb guitar cable here is my journey to fix a toy into something better. https://www.ovenwerks.net/hardware/GuitarUSBhack/index.html I find it amazing that the manufactures would not reduce their parts count while making a better product.

[ANN] Qtractor 1.5.5 - A Mid-Spring'25 Release

by Rui Nuno Capela

Hi everyone, Qtractor 1.5.5 (mid-spring'25) is out! Change-log: - Fixed negative time values displayed in tool-tips, when dragging the rubber-band (lasso) to the left, over the absolute beginning of the timeline. - A warning is now issued when an audio self connection is made (eg. connecting an output bus (or insert send) directly into an input bus (or insert return). - Files item selection mode switching corrected. - Mitigate or postpone a 'too many open files' condition as much as possible. - Let muted clips show the "[Mute]" tag as the name label prefix, so that it's visible even on small clips. - Stepping up next development cycle (Qt >= 6.9) Description: Qtractor [1] is an audio/MIDI multi-track sequencer application written in C++ with the Qt framework [2]. Target platform is Linux, where the Jack Audio Connection Kit (JACK [3]) for audio and the Advanced Linux Sound Architecture (ALSA [4]) for MIDI are the main infrastructures to evolve as a fairly-featured Linux desktop audio workstation GUI, specially dedicated to the personal home-studio.

Do you think music is getting noisier over the past 50 years?

Turn up the noise: Why distortion in music is growing in popularity by Ethan Kung, University of California, Los Angeles https://phys.org/news/2025-05-noise-distortion-music-popularity.html I guess I did my little bit part in the 1970s, running my Hammond organ output through a wahwah pedal > volume control pedal chain to an amp and making Hendrix guitar sounds.

1/4 inch to USB audio interfaces

by Len Ovens

There are a lot of "guitar" to USB "cables" out there. I picked one up just for practice purposes: plug it in to my laptop and run it through Guitarix. My findings: The board inside is a standard phones and mic usb dongle. So pipewire will try to make the phones jack (which doesn't exist on these things) the default output. Lucky for me there is an input only "profile" I can set pipewire to. Next thing I noticed was that my volume pot was scatchy... I just bought this guitar and it is not scratchy on the amp or through pedals. Yeah, the volt meter says 3vdc going to the guitar. The chip inside says it is a C-Media HS-100B. The board inside is like I mentioned, meant for a "computer" mic and seems to have followed exactly the schematic snip in the c-media application notes: Input has a varister and .1uf cap to ground and then goes through two 8.2k resisters, one then goes through another .1uf to micin... so far ok. However, the other 8.2k is followed by 47uf cap to ground (effectively making the input 8.2k) and then through a 2.2k to vbias. NOT a good input setup for a guitar at all. I could not find out what the inout impedance is of micin is but if I can get the case open (enter the dremmel) and remove the R12 to vbias, my input impedance will at least double. I'll let people know how that goes. So, 1/4inch to USB cable are not Guitar to USB cables.... put a preamp in front.... a looper for practice in cludes an aways on buffer.

NeuralRack v0.1.7 released

by Hermann Meyer

NeuralRack is a Neural Model and Impulse Response File loader for Linux/Windows. It supports [*.nam files](https://www.tone3000.com/search?tags=103) and, or [*.json or .aidax files](https://www.tone3000.com/search?tags=23562) by using the [NeuralAudio](https://github.com/mikeoliphant/NeuralAudio) engine. For Impulse Response File Convolution it use [FFTConvolver](https://github.com/HiFi-LoFi/FFTConvolver) Resampling is done by [Libzita-resampler](https://kokkinizita.linuxaudio.org/linuxaudio/zita-resam… New in this release: - add CLAP support - add option to handle presets in stand-alone version ![NeuralRack](https://github.com/brummer10/NeuralRack/raw/main/NeuralRack.png?raw=true) Neuralrack allow to load up to two model files and run them serial. The input/output could be controlled separate for each model. For tone sharping a 6 band EQ could be enabled. Additional it allow to load up a separate Impulse Response file for each output channel (stereo). Neuralrack provide a buffered Mode which introduce a one frame latency when enabled. It could move one Neural Model, or the complete processing into a background thread. That will reduce the CPU load when needed. The resulting latency will be reported to the host so that it could be compensated.

Emulating guitar gear

by Goran Mekić

Hello, I spent some time researching Neural Amp Modeler (NAM) and Impulse Response (IR) technologies. As I had trouble finding how are those generated, I wrote a small series of blog posts with my findings. In short, I wrote how to create NAM and IR files to emulate existing gear. I am by no means expert in the field, on the contrary, this is the first time I'm doing this. I hope there are more experienced people in this field than me and if I made some mistake somewhere, they'll point it out. Enjoy! https://meka.rs/blog/2025/04/15/neural-amp-modeling/ https://meka.rs/blog/2025/05/11/impulse-response/ https://meka.rs/blog/2025/05/12/impulse-response-sweep/ Regards, meka PS. There are few comments on how to make FreeBSD perform better in audio production, but it's all jack, ardour, audacity and lv2, so the choice of operating system shouldn't be important.
