Garbling and distorting voice with (or without) sox

I may be wrong but this sounds to me like a simple ring modulator.

Fixing distortion and low fidelity on a re-recorded audio cassette

Nothing posted by Schizomorph is wrong - if it's busted, it's busted... However, one small ray of light is azimuth/stereo balance correction in software. Back in the old days I had a bit of freeware (...

Fixing distortion and low fidelity on a re-recorded audio cassette

I'm afraid you can't re-construct information (in the waveform) that has been distorted. The one side you can improve is playback quality by using a decent tape player with a good head. Tape ...

What distortions are present in this audio file?

It looks like two unbalanced signals have been added together by just joining the wires together. The + sides added have hit the power rail and become flattened. The - sides added have made an "...

How to recreate the lead/distorted bass in Awolnation - Sail?

The base of the bassline is a sawtooth wave. In order to recreate the bassline I used 2 Oscillators. One peek wave for maximal crispness and a sawtooth wave transformed 1 octave lower to add weight. ...

Is it possible to fix such level of corruption in a buggy audio recording (sound distorded-choppy-Laggy)

No, I don't think you can fix that unless you have a fully equipped studio for forensic analysis, very good ears and a LOT of time. What you're hearing has a number of problems. The greatest is that ...

How to know if studio monitors are loud enough?

Your first priority here should be your own hearing. Check the actual sound levels in the room. Listening to anything over 75dB for prolonged periods (as we doo with music and sound design) WILL cause ...

How can I automate finding bass distortion in improperly processed files?

Here is my understanding of your problem: You have a set of recorded audio files stored using a lossless audio format. I will assume that no saturation/clipping occured during the recording process, ...

"Frequency Response" on a speaker datasheet provides only range. What do we assume here?

The lower and higher bounds of the frequency response are typically frequencies where the response is typically -3dB or -10dB (not all data sheets use the same convention). Whether this is measuring ...

How to know if studio monitors are loud enough?

First, JBL104 use 4.5" woofers. The amount of air they can move is rather limited. Their reproduction starts at 60Hz which is way above the fundamental of most bass instruments. There is no ...

Guitar rig settings to get a deathcore sound on guitar

You are off to a good start, but you need more. A death metal set up I occasionally use (can't remember where I got it from originally) is as follows: Compressor - Volume about 1/2, Sustain about 1/3 ...

Does it matter if RMS meters hit red?

RMS is old school now. You should preferably use a plugin that measures the loudness in LUFS or LKFS. These are the same values only in Europe they use the name LUFS and in USA LKFS. For a target ...

What are the audio settings that affect distortion on abrupt stop?

You need to re-edit the sound and implement a very short fade-in and fade-out at the start and end of the sample.

What are the audio settings that affect distortion on abrupt stop?

Without seeing the waveform, the best guess is it could be DC Offset, or it could be a limitation of the audio engine. If a waveform is at any non-zero value when the sound is abruptly stopped, then ...

What do you call the problem with this audio from cassette tape, and how do I fix it?

This is a problem that occurred during the original recording. Sounds very much like the tape capstan rubbers are slipping and the tape is not being kept up-to-speed during the recording. There is ...

Is it possible to automate removal of hum and distortion in audio files?

Distortion in the form of clipping would be very difficult to remove: the waveform has been altered, and information on the missing part of the waveform has been lost.

Is it possible to automate removal of hum and distortion in audio files?

Depends on what sort of result you want. Sure you can analyze whether a file contains more than a reasonable amount of 50Hz or 60Hz and you can notch that out, but the problem with this approach is ...

How to deal with clipping/distortion in a custom synth app
