Or use LSP Latency meter developed by CrocoDuck.

Re: LSP Project

OK, here's the answer: The Tilt setting tilts the measured spectrum around 1 kHz with a specified slope, expressed in dB per octave. The default setting of 4.5 dB/oct results in a natural looking spectrum, resembling best how loudness is perceived by the human ear. But: The frequency spectrum of pin...

Re: LSP Project

It seems that e.g. brown noise scales the spectrum by +6dB per octave and purple noise (which is violet noise?) by -6dB / octave. Other DAWs like Renoise or plugins like Fab Filter use a scaling of +4.3 or 4.5dB per octave which results in quite a flat spectrum. Yes, 'purple noise' is in fact 'viol...

Hmm, no problem here to see them, they be there for the next 2 years.


It seems, that russian providers are blocking the resource where you've placed pictures.
From foreigh proxy they are shown well.

Re: Go-DSP-Guitar multichannel multi-effects processor

TL;DR I understand, you've inspired with Go (wow, that's easy to build applications, code doesn't bloat, never need shuffle bytes as in C, etc...) but I'll just leave this link here: https://cellperformance.beyond3d.com/articles/2008/03/three-big-lies.html I don't want to argue with you for a long w...

Re: Go-DSP-Guitar multichannel multi-effects processor

The FFT-algorithm is indeed heavily optimized. You think that it's heavily optimized. But actually it's not. Consider such FFT optimizations: https://github.com/sadko4u/lsp-plugins/blob/master/include/dsp/arch/x86/avx/fft/p_butterfly.h https://github.com/sadko4u/lsp-plugins/blob/master/include/dsp/...

Re: Go-DSP-Guitar multichannel multi-effects processor

As an R&D project it would be OK. But the final performance of your software will be poor. I'm currently talking about DSP algorithms like resampling: https://github.com/andrepxx/go-dsp-guitar/blob/master/resample/resample.go And FFT transform: https://github.com/andrepxx/go-dsp-guitar/blob/mast...

Re: recording EQ, compressors, etc plugins

The routing should be:
Audio source -> Ardour bus with EQ, compressor, etc -> recording track.

Re: are you always listening at 83dB SPL? aka/ ISO 226:2003 based loudness compensation

yea, the EQ/convolver needs a diferent curve every 5dB or so. It needs a proper volume control which will change the curves when changed. an EQ/convolver software with a switch to change between (6 or so) curves would actualy do the job the dev explains the theory here: https://github.com/dpapavas/...

Re: are you always listening at 83dB SPL? aka/ ISO 226:2003 based loudness compensation

Do I right understand that you need an Equalizer which will have different equalization (according to the loudness curve) depending on the gain settings?

Re: HOWTO: Quick Frequency Response Measurements Using JAPA and Faust

whats your opinion on the EQ vs convolver question? According to the DSP theory, convolution is another way to present the frequency characteristics of the linear system. But parametrized filters have two huge advantages: - parametrized filters can be simply edited by adjusting their parameters; to...

Re: HOWTO: Quick Frequency Response Measurements Using JAPA and Faust

@sadko4u: Just to make sure that it's correct, what I'm doing: When saving the filter.req file from REW I have to choose the GENERIC filter type, right? When importing this into your EQ it automatically jumps to APO. In here I have to choose PK, I guess (as written a page above from here): https://...

Voice of Sands - Зеркала (Mirrors)

One of our rare song recently recorded in a rehearsal room - Зеркала (Mirrors).
Currently without vocals but we've already found female vocalist and going on!
