One such application would be a CV to controls(Midi,OSC,whatever) converter. As

Hello Alan,you might want to look into time-varying filters.
The range of possibilities for time variant filters is so wide that stability

filters or on a specific field of application. Furthermore, the main concern

Hi,I am one of the developers.Sure you can use your editor of choice. The
browser-based IDE is a convenient, ready-to-go solution which acts as a
front-end for the building scripts we provide, which build the code on the
board. The scripts can, alternatively, be reached through the command line,
Hello,I watched the google/android video the other day and I was very surprised
of the basic recommendations that were given to developers:- use native
sampling rate (don't hardcode sampling rate, request it from the device)
- use native buffering (don't hardcode it. But then maybe use double or

BeagleBone's Cortex A8 we use:
-O3 -march=armv7-a -mtune=cortex-a8 -mfloat-abi=hard -mfpu=neon -ftree-vectorize
my notes on this are:

Also, only way to actually know if your compiler generates Neon is to ... read
the assembly!
Some common DSP tasks are implemented in the Ne10 library
http://projectne10.github.io/Ne10/doc/ which compiles to Neon on systems that
support it.
I have seen that nova_simd is good at generating neon c
No pun intended

Hi,I actually implemented this a few years back using an FFT algorithm, I can
dig out the code if you need it (it was a VST written using Juce and fftw, but
there was no threading on the FFT if I remember correctly, so it is flawed as
it is and it requires running with large blocksizes.I doubt s
tweaks to shift, stretch and randomize the spectrum. It
runs nicely on an STM32F405 ARM Cortex M4F processor.

I'd love to have a go at doing this kind of stuff on something like a
SHARC where 16kpt FFTs are apparently easy to do at audio rates...

Perhaps only tangentially related, but Bela - of which I am one of the
developers - comes with a browser-based oscilloscope as part of its IDE. This
allows you to generate both analog inputs and internally, digitally-generated
signals, e.g.:https://www.youtube.com/watch?v=o9kLZ--js1k

The functions here
https://github.com/BelaPlatform/Bela/blob/master/core/math_runfast.c will allow
to manipulate "fast" mode for ARM vfp (making it non-IEEE-754 compliant). If
you are using the NEON SIMD (you should!) then it always flushes to zero (which
is one of the reasons why NEON is non-c
