How long do you expect the blocks to be?
would this be a running similarity? i.e. every N ms you up date the similarity of the most recent M ms of signal

Re: Looking for XMOS firmware developer for digital mixer
If it helps, we have a DSP and DSP effects library for implementing effects such as reverb.

Re: Upgrading from Propeller
The xcore would be an idea chip to use for these applications, and the 50mS is easily achievable.

Re: Double xTIMEcomposer Studio Registration
The login is to allow us to know which versions of the tools are active so we can know how far back we need to maintain support for. If no one is using old versions, after a while, we could choose to deprecate them.

Re: questions about XMOS MCU and ultrasonic digital microphone
The library has an intermediate format of 384kHz which is accessible over channels. This format is not normally ideal as it contains a lot of alias noise. Alternatively the library can output at 96kHz but you will not get up to 80kHz. You do have the option of taking the 384kHz signal and decimating...

Re: dsp_vector library inconsistency
Normally, when working in the frequency domain I work with complex multiplications meaning I will use: dsp_complex_mul_vector() or others from dsp_complex.h. In your case if you would like to use dsp_vector_mulv_complex() then I would recommend writing a type for deinterleave and interleave function...

Re: MADI (Multichannel Audio Digital Interface)
It is possible given a suitable physical interface. The timing seems within the capabilities of our physical interfaces. The only questions is would it fit in a single core or require two? Two would mean that you could easily decouple the protocol layer stuff from the physical encoding, i.e. how the...

Re: dual issue
-O2 should be on by default for xTimecomposer projects.
If you really need speed then assembly coding your I/O can give massive speed ups.
