Simple cheap USB Microphone / Soundcard

Yeah very far from clipping, in fact the other way a tad to low as the further away the less that will become.

I have been having a search around but its all very much the same.

Noisetorch https://github.com/lawl/NoiseTorch & https://github.com/josh-richardson/cadmus are non gpu based like RTXVoice which actually will run with any Nvidia from about 780 and above I think.
Seems to even work with my 1050TI even though input volume seems low.

Also https://github.com/wwmm/pulseeffects

But they are all desktop and think X86 but I have thought for a while now that WebRTC AEC is woeful purely because the Pi lacks the ooomf or even though it compiles the AEC isn’t the same as it runs on X86.

But maybe you can get https://github.com/werman/noise-suppression-for-voice installed and use pulse audio as you can make alsa use pulse also.
The above is a Linux non nvidia RTXVoice but again how well it runs and if will need to be tried.

There is a whole rake of technologies from tensorflow vad that I have said before the same FFT routines of MFCC creation are all very much similar and its very much too much load because these routines are being run separately for each element in different threads but could reduce load much be utilising a single fft routine.
Its all beyond me C which is non existent and would seem beyond Rhasspy because its non existant.

My opinion is that just about everything is wrong here from non existent audio processing to vad choice to infrastructure.

I post every now and then as a single usb sound card and uni-directional mic (prob a better electret than the china ones I tested) is prob best you can get before spending big $ on DSP silicon.
But even then in comparison to more horsepower and what you can do with a GPU is that spend worth it? Is this infrastructure worthwhile?

My opinion is probably not so hence I am going to run and keep stum.

I will post occasionally about simple cheap soundcards and the best available electret you can get. (PS there are uni-directional dual port mems but never seen one to source but they do exist).

The case on the el cheapo white one if you run a scapel blade around snaps open clean and pretty easy.

If I was to take 5v from there I would prob run outside the current screen as was think about using the spare bias core but maybe is a bad idea than leaving the output alone and screened.

You can still run from gpio but if you want to keep that clean tacking onto 5v is pretty easy.

Yes and I don’t know how to rise capture level, being at max gain level I’m also not sure setting capture gain at max won’t induce distortion (doesn’t seems so in the waves)

Next time I will do same test with some sentence corresponding to some intents, and test the wav into rhasspy.
As my voice is quite clear on top of music, I guess rhasspy will manage to recognize intent. Which would mean that with a max_duration settings for listening it would stop listening, and send the audio to ASR which could then work !

I don’t know if it’s possible that before wakeword, rhasspy (always listening for wakeword) detect average sound level, and after wakeword cut such level to better detect silence. But a max_duration for listening around 6 or 7 second, even less, would cut it without silence detection and make things a lot better. Really hope @synesthesiam can implement such max_duration user settings like actual min_duration, speaach before, silence after etc settings.

Yeah that a really great idea as basically when we have Vad=!voice the rms should create a noisegate if vad=voice.rms - vad=!voice.rms > voice.ceiling.

You can create a noise gate by a right rotation without carry and just drop LSB’s, then rotate back with zero’s replacing.

My C & Python sucks almighty its not even hacking but molesting so might leave to someone else

PS apols @romkabouter as posted beamformers and totally forgot about

JGKK · December 19, 2020, 10:27am

Thats funny I actually have to lower the gain on all of my 2mic hats as otherwise I get horrible distortion and clipping when closer than 1.5 meters.

Do you want to give another group session a go as we can test the difference between yours my clone and kibo’s.

do a amixer -c 'my card index' contents and will try a recording

amixer -c2 cset numid=1 50,50

Sort of normal clear voice @ .5m exact approx 78db @ mic

Its painful to listen too. About 70 cm from mic

Yeah we are getting things mixed up but dependent on volume of what you are recording I had approx normal talking volume but hard to judge but measured @ mic 78db

The above was just a replay that entered a quote but was with

amixer -c2 cset numid=1 32,32

JGKK · December 19, 2020, 12:37pm

@rolyan_trauts here is with mysettings of numid 1 32,32 and numid 28 2
https://drive.google.com/file/d/1vnX_B8ffhzTBbMz0vKAZKUvayqe785_a/view?usp=sharing
Both are normal talking volume and same distance

rolyan_trauts · December 19, 2020, 12:41pm

Yeah but unless you have alc on numid=26 numid=28 does nothing.

JGKK · December 19, 2020, 12:45pm

which still leaves the question why numid 1 50,50
gives consistently horribly results for me and not you guys

rolyan_trauts · December 19, 2020, 12:47pm

Dunno but will have to see what kibo sends.

Each time even though a pain send amixer -c 'my card index' contents so no mix up between example and settings

JGKK · December 19, 2020, 1:15pm

Do you know what the units of the alc hold time are?
ms?

AUTOMATIC LEVEL CONTROL (ALC)
The WM8960 has an automatic level control that aims to keep a constant recording volume
irrespective of the input signal level. This is achieved by continuously adjusting the PGA gain so that
the signal level at the ADC input remains constant. A digital peak detector monitors the ADC output
and changes the PGA gain if necessary. Note that when the ALC function is enabled, the settings of
registers 0 and 1 (LINVOL, IPVU, LIZC, LINMUTE, RINVOL, RIZC and RINMUTE) are ignored.

The ALC function is enabled using the ALCSEL control bits. When enabled, the recording volume can
be programmed between –1.5dB and –22.5dB (relative to ADC full scale) using the ALCL register bits.
An upper limit for the PGA gain can be imposed by setting the MAXGAIN control bits.
HLD, DCY and ATK control the hold, decay and attack times, respectively:
Hold time is the time delay between the peak level detected being below target and the PGA gain
beginning to ramp up. It can be programmed in power-of-two (2
n
) steps, e.g. 2.67ms, 5.33ms,
10.67ms etc. up to 43.7s. Alternatively, the hold time can also be set to zero. The hold time only
applies to gain ramp-up, there is no delay before ramping the gain down when the signal level is
above target.
Decay (Gain Ramp-Up) Time is the time that it takes for the PGA gain to ramp up across 90% of its
range (e.g. from –15B up to 27.75dB). The time it takes for the recording level to return to its target
value therefore depends on both the decay time and on the gain adjustment required. If the gain
adjustment is small, it will be shorter than the decay time. The decay time can be programmed in
power-of-two (2n
) steps, from 24ms, 48ms, 96ms, etc. to 24.58s.
Attack (Gain Ramp-Down) Time is the time that it takes for the PGA gain to ramp down across 90% of
its range (e.g. from 27.75dB down to -15B gain). The time it takes for the recording level to return to its
target value therefore depends on both the attack time and on the gain adjustment required. If the
gain adjustment is small, it will be shorter than the attack time. The attack time can be programmed in
power-of-two (2n
) steps, from 6ms, 12ms, 24ms, etc. to 6.14s.
When operating in stereo, the peak detector takes the maximum of left and right channel peak values,
and any new gain setting is applied to both left and right PGAs, so that the stereo image is preserved.
However, the ALC function can also be enabled on one channel only. In this case, only one PGA is
controlled by the ALC mechanism, while the other channel runs independently with its PGA gain set
through the control register.
When one ADC channel is unused, the peak detector disregards that channel

Sort of hard work but start at minimium and double on each step.
