Summer Audio hacking with the esp8266

July 4, 2017

Wemos Audio

Today we start a series of articles on creating synthesizers with the esp8266.

The esp8266 is quite powerful for audio applications with a CPU frequency of 160MHz and 4MB flash and easily outperforms the Volca Sample with a WiFi/Web GUI.

We will use the Wemos D1 Mini board with the Arduino IDE and all the source will be available.

The series starts off today with creating the 44.1KHz, 16-bit PDM Audio DAC.

If you have no clue about soldering but still want to follow you can order the Wemos D1 Mini with a 3.5mm Audio jack prebuilt.

Order the Wemos D1 Mini Audio $10

Here is the series

Happy hacking!

SSI2144 now available in single quantities

May 23, 2017

SSI2144VCF

The SSI2144 reprises the SSM2044 of legacy chipmaker Solid State Microtechnology, which many believe to be the best-sounding analog synthesis filter IC ever produced.

Based on Dave Rossum’s patented classic improved ladder topology, the SSI2144 allows rich tonal characteristics that showcase the very best attributes of subtractive synthesis.

The SSI2144 uses the same internal circuit as the SSM2044 but in a SSOP-16 package.

It is now available at DSP Synthesizers in single quantities for DIY projects.
There is also an adapter PCB for converting it to a DIP-16 SSM2044 replacement to upgrade or repair vintage synthesizers.
