New needs for VoiceAI preprocessing by old tools
...ication occurs and increases load.
The Alsa-plugins of Speex echo just don’t seem to work whilst repos using the speex libs do.
https://github.com/voice-engine/ec
I actually use the speex AGC Alsa-plugin as its a great tool and then run Echo via the above.
Coupled to WebRTC_VAD and a python based MFCC routine.
Beamforming and DOA I have given up hope for as I am running so many extremely similar FFT routines concurrently in different process space that my load usage makes me believe there isn’t a chance.
All of them have extremely similar frame based spectra analysis collection that collate and...

new versions of packages RWinEdt, signal, tuneR
...fixes,
documentation improvements and hundreds of test cases - many thanks to
Sarah Schnackenberg for most of the work!
- tuneR: After tuneR got mp3 read support last year, we managed to
include support for mel/bark/hertz scales and conversion, powerspectra,
as well as full support of LPC and MFCC coefficients (and some other
stuff). Note that the former code that was documented as "experimental"
for MFCC calculations has been replaced and the API changed. Many thanks
to Sebastian Krey for the contributions!
On its way to CRAN is:

using vorbis for finding structure in music
...iptors in order to find repetition and
maybe also transformations. Currently I am using descriptors that can be
described as a small subset of the FFT of the FFT, which gives me a
not-too-many-dimensional vector for one second of sound, with a stepsize of
0.1 second. I am also thinking of using MFCC, but it might be more
interesting to start with the Vorbis data, and process them. Maybe do an FFT
on them, in order to diminish the amount of data.
The advantages are that all the soundfiles I want to process can be stored as
.ogg, and the decoding into raw PCM audio can be skipped.
Another a...
