harmonic distortion

My home audio chain is mostly digital and looks like: [PC] -> [USB to SPDIF] -> [digital equalizer] -> [digital crossover + DACs] -> [power amps] -> [subs and mains] I recently bought the Topping D10B for USB to SPDIF conversion, and that offered a possibility to apply the Behringer SX3040 V2...

To test the audibility of pure second-order distortion I have written a Foobar plugin which simulates a quadratic transfer function. On the configuration dialog of the plugin, you can set the desired level of the second harmonic in 24 steps between -150dB and -12dB and also turn it off...

Hello. On Rtings reviews there are weighted harmonic distortion graphs. Could we use that data to somehow modify the audio signal to try to remove the harmonic distortion? If so, is there a program or maybe a Matlab/Python script that applies such correction to audio files? Would there be any...

As part of a study of the effects of non-linear distortions in amplifiers, I came across an aspect that left me a little perplexed. This is the way in which the THD value (and also the IMD and TD+N) of the data collected by the standard measurements is calculated. Measurement of distortions in...

I have the habit of choosing “brickwall” filters when setting up my DAC, but when looking at measurements, filters that are -100 dBFS at 22 kHz usually have worse THD vs. Freq performance than slower filters (the ones at -100 dBFS at 24 kHz). I think this is due to the wideband harmonic...

Introduction In the engineering of electronic devices for music production or reproduction all designers are faced with the problem of minimizing the different forms of distortion inexorably introduced by their creations on the audio signal. They are commonly classified into two categories...

Hi all! I've been hearing some strange things lately on out of my Aune X1S. I can't seem to find it inside of ASIO4ALL and there are strange distortion spikes. The first image is my onboard soundcard and the second one is my Aune with the fast filter selected. I just want to know if this could...

Hypex UcD180HG HxR module analysis and review After buying and testing AIYIMA A07 amplifier (based on TPA3255 class D chip) in January 2021 I was quite disappointed with the frequency response modulated by speaker complex impedance and its audible consequences. This is, unfortunately...

I have been thinking about headphone drivers/transducers that regardless of frequency response if fixed by EQ (assuming other measurements to be good enough), they became great. One of these examples is the AirPods Max, it is a pretty accomplished driver but its frequency response curve is not...

From 4:25 to 5:00 DMS said: "In the recording end things like harmonic distortion is sought after. Some very expensive and well rounded microphones add significant harmonic distortion, then are plugged in through tube amps to power microphones - tube compressors and processed through different...

Hey folks, asking for your feedback in an informal poll. If you know about my DISTORT software (https://distortaudio.org) you know that it allows an arbitrary harmonic distortion to be constructed and applied to any test signal or a music track of your choice. Some have used this capability...
