Re: [music-dsp] Low cost DSPs

Spencer, The CS4270 is an ancient but decent codec that I've found to be less noisy than the WM8731. There are many others of course. Fabian, This depends a lot on what you have in mind when you say "low delay". * In PCs, much of the audio latency comes from the OS audio drivers and

Re: [music-dsp] Low cost DSPs

Hi Eric, hi Spencer, I have a related question: can you recommend any multichannel codec that works nicely with STM32 for the application of low delay mixing: lets say 8in/4out? Is the stm32 capable enough for this application? best Fabian On 20 Feb 2017, at 10:04, Spencer Salazar

Re: [music-dsp] Low cost DSPs

Hi Eric, I would definitely be interested to hear more what you'd suggest to improve the ADC side of things with STM32 + codec, as far as a low-cost HW/FW audio prototyping platform. spencer On Sun, Feb 19, 2017 at 6:22 AM, Eric Brombaugh wrote: > As the author of one of

Re: [music-dsp] Low cost DSPs

As the author of one of the pages listed below I'd note that STM32 + codec is a fairly capable combination. I'd caution however that the WM8731 may not be the best choice - the DACs are fine but ADC side is fairly noisy. It's probably fine for some things, but with a little care and a few extra

Re: [music-dsp] Low cost DSPs

STM32 ARM + Wolfson WM8731 codec is popular in the modular synth community, e.g.: http://mutable-instruments.net/modules/clouds/ https://github.com/pichenettes/eurorack/tree/master/clouds/hardware_design http://ebrombaugh.studionebula.com/synth/stm32f4_codec_v2/index.html and I think:

If you target modern GPU:s you will have a truly huge platform with massive computational power. Just a thought. On Thu, 16 Feb 2017 at 05:03, Pablo Riera wrote: > Hi, > > I am collecting information on how to accomplish DSP projects (mainly > synths, only output) with

Re: [music-dsp] Low cost DSPs

Xmos dev boards are also something to think of. You lose the easy "Hey there is a ready-made library for almost everything" you have with Teensy or Arduino, but you gain a lot of processing power for little money. I have used the cheapest one: https://www.xmos.com/support/boards?product=17441

Does anyone has experience with some of these combinations or others Teensy + audio board is popular too. and could share comments on technical issues, ease of use, latency, audio quality (noise, max sampling rate), etc. I’m working on something using a Raspberry Pi 3 + USB audio. Latency
