Which is the better recording of this song?

There are two issues here. Both claim to be 44.1k FLAC files, yet the first graph clearly goes over 22KHz... which is, if not impossible, rather unlikely. Technically, it could all smooth out before ...

mp3 spectral analysis blue above 16 khz

Everybody seems to have this obsession with looking at pictures of sound. You can't tell what something sounds like by looking at a picture of it, the same as looking at a picture of food doesn't tell ...

320kbps MP3 - Why is there a clear line near 16khz on spectrogram?

Do you know what mp3 codec is being used? Frauhenhoffer/lame etc all use different techniques to compress the audio. For example, the Lame VBR, even at its highest setting V0 will cut off anything ...

How to create an audio file from a spectrogram?

You can use Coagula. I believe it is the same software Aphex Twin used in Windowlicker.

320kbps MP3 - Why is there a clear line near 16khz on spectrogram?

MP3 encoding employs psychoacoustic techniques like masking (in both frequency and time domain) to reduce the complexity of encoded audio whilst not perceptually sacrificing quality. What you're ...

Which spectrogram shows higher quality of the song?

You are barking up completely the wrong tree. This is sound. We don't hear sound with our eyes, we listen with our ears. You cannot tell whether a sound is "better quality" than another sound by ...

How to cancel out sound in an audio track?

Total phase cancellation [which is what you appear to be looking for] only works in mono. Each time one channel has a positive voltage, the other has an identical negative voltage. When summed to ...

How to interpret the spectogram from spek

The only information I could possibly garner from those three spectrograms is that it's a reasonable possibility that the WAV wasn't the original source file. There's evidence it has already had a ...

from Flac to wav

FLAC is lossless compression. During compression, you can set a compression option: setting this to a higher level creates a smaller file that is still lossless by taking more time to process the file....

Isolate hoots seen in spectrogram

You could try a high pass and low pass filter, and noise reduction. Then amplify the result if needed. For the high pass filter try a frequency of 400 Hz and for the low pass try 700 Hz. This gives ...

Can spectrograms tell us why one song is "more dynamic" than the other?

TL;DR? Skip to "In Summary" Analysis in Numbers Simply put, dynamic range is the difference between the lowest and highest amplitude values of a given audio signal. - You could say it's the ...

How to consistently increase or decrease the volume of a chosen harmonic frequency

By utilizing a pitch tracker to follow the base frequency of the target sound, then using that info to drive the frequency of a peak filter after the appropriate multiplier.

Spotting a fake flac using spectrogram

This looks "extended" because of the (most probably) linear scale that your spectrogram is using on the frequency axis. It should look way more common if you switch it to log or similar. @...

Comparing two spectrograms

I've been looking at this for a couple of days and it just came to me. You could subtract the two waveforms and get the spectrogram of the difference. In theory it should be the same as what you asked ...

Why does this spectrorgam look so jagged?

lol, those "strange lines" (horizontal) are harmonics; and because this spectrogram is scaled linearly, they're evenly spaced; if it was scaled logarithmically, it would closer represent what we hear. ...
