How do I fix a robotic reverb/delay in a recording?

It's peculiar - the tops of the vocal bits are chopped off in the spectrogram in very deliberate chunks. I wonder if that's a file compression thing. But anyway, first, I'd remove the noise (learn ...

Denoising studio induced noise and noise due to poor recording

Firstly, do any and all processing in WAV files. If your source material is on CD, then rip to 44.1kHz/16bit WAV and process at 24-bit in your software. Do not transcode via mp3. Tracks like 104b ...

"Move" waveform "up"/"down"?

Yes, you can definitely fix the majority of the pop on that one by effectively removing the DC offset that is in there. Most DAWs will let you do this - it can be a bit fiddly, but the aim is to zoom ...

How can I fix robotic distortion from an audio track?

Buffer underrun might have caused that distortion to the audio. Buffer values can be increased in the audio driver section of the software or DAW you're using so that the issue disappears when ...

Audio restoration with very poor signal to noise ratio

Amplification of the digital signal won't make any difference to the de-noising process other than introduce the possibility of signal clipping, which will further degrade the signal. Recommend you ...

What are the best practices for sequencing the Isotope RX7 Standard toolset for dialogue audio restoration?

The list of activities you describe is pretty much the right way to approach this, although data corruption is not an easy artifact to correct. I would recommend removing any DC component as the ...

How can I send an audio re-recordered by whatsapp without distortion

What you want is to create an audio file that, when played through a speaker that distorts, somehow compensates for that distortion. That's generally impossible, because the distortion is an ...

Is there way to improve R sound in audio?

In general, to lift consonants, you have to push back the vowels, otherwise things can just get 'fizzy'. You could try this with EQ - lifting somewhere between 1 - 4kHz, but I think that's more likely ...

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 ...

How do I detect the sound files used in an audio file?

It's likely that the final audio file was not just a raw "addition" of the original files, and it was 'mixed' using various techniques (EQ,compression etc.) Therefore it's very unlikely you will be ...

How to restore damped high band?

You need to post an example. This could be due to low quality variable bitrate - and those "bits" are just gone. Trying to boost the missing areas will just bring forth bad artifacts. If this is an ...
