Hypex DSP Memory Map

TrueSound Project 25 Sessions · ~85 hrs
Gen1 — FW 1.x
Original FusionAmp platform. 15 biquad filters per channel, 3 presets. Solid workhorse — still in production and widely deployed. No FIR capability.
Gen3 — FW 5.x
Hardware redesign forced by the AKM factory fire (Oct 2020, Nobeoka, Japan) — Asahi Kasei's semiconductor plant burned for 82 hours, destroying the world's primary source of high-end audio DAC/ADC chips. Hypex redesigned around the Analog Devices ADAU1452, gaining FIR filtering — up to 4,500 taps for correcting speaker driver time-domain delays and phase response.
What is this?
This interactive map catalogues my last week of program development — I am creating a replacement tool for the Hypex (brand) amplifiers that I use in all of my self-powered speaker systems. Hypex makes incredible hardware — some of the best amplifiers and processing available. Their software on the other hand is an absolute nightmare.

The Hypex supplied tool for building tune files (required to actually use the amplifier) has been a MASSIVE source of frustration for me over the last several years — it has SO MANY BUGS and constantly causes you to fail at getting a job done. This new tool is a game changer for my work flow, and can literally turn a 2 hour job into a 5 minute affair. It even improves the quality of my work, and lets me spend more time doing the thing I actually want to be doing — Building cool stuff.
