What you are asking is impossible to determine from a spectrogram. Spectrograms indicate frequencies present, not the quality of the audio. There may be loss of fine detail in one that would barely show up on a spectrogram at all or there could be noise and artifacts introduced that would make the spectrogram look more full. Spectrograms do not ...

this is quite informative: http://www.soundonsound.com/sos/may00/articles/mp3.htm The gist is: as long as any signal can be represented as the sum of sine waves (Fourier's work), and as long as you can deconstruct any signal back to sine waves (FFT, DCT math), then you can use a different way of encoding just the data that's required to reconstruct an ...

Random data is hard to compress because it is random, data with a pattern is easy to store. Audio data itself appears fairly random at first, but in actuality there is a pattern to it. Additionally, when you allow certain details to be altered in ways that are not that noticeable to listeners, you can make it fit a pattern that is far easier/smaller to ...

Best audio quality is difficult to assess objectively. What you can say from the given audiograms is (as you mentioned) that N° 3 includes more high frequencies, which is usually considered better. About the N° 2 audiogram : there's usually no benefit in transcoding a lossy file into another lossy file codec because whatever information has been lost in ...

This is simply the way that the brain processes sound information. It's exactly the same as listening to a violin in a dry anechoic environment and then listening to the violin in a concert hall. You still know it's a violin because the brain is able to separate the fundamental sound from the additional reflections in the room. It's the same with distortion ...

Do you let it play note on repeat when designing sound? I push the keyboard myself and I found that much better than let it loop the note and sculpting your sound. I often can't resist to go wild with the keyboard too, which is fun and often rewards me with desirable sound.

Suppose you want to save the following sequence of numbers: 0123456789 0123456789 You can store those numbers individually, which would be equivalent to how uncompressed .wav or .bmp works. But, if you agree on certain rules and define those in a certain format (like mp3), you can also save these numbers without explicitly writing down the value of each ...

His wording is confusing, but he does mean that the two channels, the original and the duplicate, should be panned hard left and right. The whole point of using the Haas effect is to maintain the even levels of a mono signal, but fooling the brain into locating it either left or right. I’m not sure if you understand how the Haas effect works or not. I’ll ...

Psychoacoustic compression (mp3 for example) works by removing the parts that you don't hear. That means if there is a loud signal you won't hear a quiet signal that is shortly after. For that time you do not need to save information. Same thing frequency based. If you have a very loud frequency, then you won't hear a quiet frequency nearby. So you have ...
