Teensy audio bar 154/25/2023 ![]() ![]() Band-Limited Sawtooth Oscillator on the Teensy This tutorial walks you through the steps of synthesizing sound with Faust on the Teensy. Hence, we strongly recommend you to use the Teensy 3.6/4.0 for this (things will work on the 3.2, but computational power will be extremely limited). The main consequence is that this system will only work efficiently if it's used on a Teensy board hosting an FPU. Since Faust is currently not able to produce fixed-point DSP C++ code, generated object use floating point arithmetic internally. faust2teensy can be used to implement new objects for the Teensy Audio Library using Faust. The current DSP objects of the Teensy Audio Library can be used to implement simple algorithms but their scope is relatively limited (i.e., basic oscillators, filters, etc.). More information and tutorials can be found on the Audio Library webpage. An online tool provides a user interface to this system and allows for the implementation of sound processing algorithms in a "Max/MSP way." Various elements can be used as the input and the output of the system (e.g., built-in Teensy DAC/ADC, audio shield, etc.). It uses a patching paradigm where DSP objects can be connected together using virtual patch chords. The Teensy/ Teensyduino comes with an Audio Library that can be used to synthesize sound directly on the Teensy. bare-metal: the lack of operating system allows for the use of very low block sizes (i.e., as low as 8 samples on the Teensy) and therefore extremely low latency,.low power consumption (i.e., can be easily powered by a battery),.Using this type of chip for embedded real-time audio DSP presents a wide range of advantages: This paper provides a survey on the performances of such system when used with Faust-generated DSP objects. When combined with their respective audio shields (also distributed by PJRC), the Teensy 3.6/4.0 can be used to synthesize and process sound with advanced algorithms, etc. Also, PJRC recently released the Teensy 4.0 which is based on a Cortex-M7 (FPU) with a clock of 600MHz and much more memory than the 3.6. In particular, the Cortex-M4 used on the Teensy 3.6 (MK66FX1M0VMD18) hosts a Floating Point Unit (FPU) and has a clock of 180MHz (overclockable at 240MHz). The Teensys 3.(2+) are based on an ARM Cortex-M4 providing plenty of computational power for real-time audio signal processing applications. The Teensy is a development board series based on a microcontroller and distributed by PJRC. DSP on the Teensy With Faust Introduction
