Voxengo Boogex

Posted by tom2tec on

Applications

  • Real-time guitar processing
  • Speaker cabinet simulation
  • Stereo convolution processing
  • Guitar reverb effect

Boogex is a free guitar amplifier AudioUnit, AAX, and VST plugin with a variety of sound shaping features, for professional sound and music production applications.  With Boogex it is possible to get a heavy distorted sound as well as slight “jazzy” saturation sound.  Boogex is able to apply convolution with any speaker cabinet impulse response (selection of built-in impulses is available).  The processing latency is close to zero making it possible to use Boogex for real-time guitar processing.

Boogex can be used as a plain stereo convolution processor when its “Amp” stage is turned off.  The convolver module has zero latency and is not CPU-demanding.  Boogex also includes the input gate module, and reverberation module derived from Voxengo OldSkoolVerb reverb plugin.

Boogex produces a nice “minimalist” rock music-geared sound which may be a bit noisy at higher overdrive settings; higher frequencies can be easily suppressed with its built-in Emphasis EQ.  With the amp modes Boogex currently provides, it is not particularly well-suited for metal music, but can still be used as a cabinet impulse response processor for metal music.

SmartGuitarAmp ~ Neural Network Hardware Emulation

Posted by tom2tec on

Guitar plugin made with JUCE that uses neural network models to emulate real world hardware.

See video demo on YouTube

This plugin uses a WaveNet model to recreate the sound of real world hardware. The current version models a small tube amp at clean and overdriven settings. Gain and EQ knobs were added to modulate the modeled sound.

Q17 ~ QUAD 405 MOSFET Amplifier

Posted by tom2tec on

Q17 is an amplifier based on the QUAD 405 current dumping principle.

Please refer to Q17 Project description from Tiberiu Vicol’s original design.

Q17-Turbo project (200W @ 8 Ohms):

The natural evolution of the Q17-Mini, this time with two pairs of power transistors, better thermal management with the same technical characteristics and the same sound signature.

SqueezeAMP ~ All In One Audio Board

Posted by tom2tec on

With the squeezelite-esp32 software, you can

  • Stream from LMS and send audio to the build-in amplifier, the line-out jack, the spdif connector or another Bluetooth speaker. You can also use an external I2S DAC if you connect it to the general purpose 5/8 pins connector and tweak the software. Synchronization works.
  • Stream from a Bluetooth device and send audio to the same outputs, except of course for sending to another Bluetooth speaker … There is no guarantee of audio/video synchronization at this point
  • Stream from an AirPlay1 device (iPhone, iTunes …) to the same outputs, including to a Bluetooth speaker. Synchronization works.
  • Add your own buttons, rotary encoder and map/combine them to various functions (play, pause, volume, next …
  • Use IR control by adding a simple receiver compatible with 38kHz device (no pullup resistor or capacitor needed)
  • Add a display like this one which can be directly connected to the 6-pins header. Currently SH1106, SSD1306, SSD1322, SSD1326/7, SSD1351, ST7735 and ST7789 displays are supported.
