Compressor vs Volume
It's important to remember that a compressor does not make a sound louder, it reduces dynamic range. By bringing down the peak values, you give yourself more headroom to bring up the overall signal ...

Volume treatment in WAV (PCM) file
If you want to be technically accurate, a sound file does not have a volume, it has a level. Volume can only exist when there is an actual speaker producing sound as that has a fixed SPL(sound ...

Convert dB value to linear scale
Practical version
dB → gain-multiplier:
g = 2d / 6
gain-multiplier → dB:
d = 6 · log2(g)
I find these definitions far more handy than the ones below: changing the amplitude ...

How can I get my direct input monitoring louder?
I doubt this is really an error – as this interface is USB-powered, the designers probably spec'd the headphone output with rather low maximum voltage, so as to avoid supply problems; I know at ...

Choosing a balance between soundtrack and voice
Personally, I prefer tutorials without music. I also think a bit of background noise is not an awful thing. Gated dialogue or over-baked noise reduction is far more distracting. Choosing a mic you can ...

How can I extract the volume from an MP3 or MP4?
As you don't mention which platform/OS you're running, I would suggest loudness-scanner.
Something like :
loudness dump -m 0.1 *.mp3 > data.txt
should provide you with a text file containing raw ...

How to adjust the volume level of the track when the automation points are already set?(Ableton/Logic pro)
To move the whole automation, you have to select the entire area of the automation first, then move it.
BUT..
This is a common problem, that pretty much everyone solves the same way.

How can I eliminate sounds below a certain threshold?
It really depends on the material; are these sounds that you want to remove truly peaking at a lower level than every bit of the speech? How about in loudness or 'energy'?
You need to look into the ...

How to change volume of a .wav file in a mp3gain-like way?
ReplayGain tags aren't standard in WAV files, so you have to alter the PCM data with the required gain.
As per my reading of the Replaygain specs, a correctly implemented Replaygain scanner will ...

What property of sound disturbs us?
Change is typically "disturbing". A sharp change of amplitude (a crash, a scream, an explosive sound, etc.) Or even sudden quiet after moderate but steady background noise will disturb some people. ...

Does a Headphone Amp Increase Output Volume?
Probably, yes. "Headphone power" depends basically on two things, output voltage and headphone impedance (I discussed it in some detail here). Many devices don't bother providing a very great voltage, ...

Free tools for normalizing the volume within a single track
Audacity does normalising but it sounds like what you want is a peak limiter. Try the Yohng W1 Limiter, which is modelled a a well-known and (possibly overused) plug-in. It doesn't look all that, but ...

Free tools for normalizing the volume within a single track
Normalisation only raises the overall volume uniformly (the soft parts will be louder, but so will the loud parts). What you're looking for is dynamic-range compression, and I think there's a plug-in ...

Choosing a balance between soundtrack and voice
You could use a gate to try and remove as much of the background noise as possible. If the background noise is in the low frequencies, try low-cutting the commentary with an EQ or filter. Audacity ...

How can I get my direct input monitoring louder?
Thanks for your answers. This is what I ended up doing:
I found out you can buy a splitter for a mic (called an "isolation transformer", $40) which allows you to use two preamps (in other words it ...

Compressor vs Volume
I'm honestly not sure what you are asking here. Compression does not increase the "volume" of a signal, it decreases it. Compression makes a quiet portion of the sounds louder relative to a louder ...

There is a “Velocity” MIDI effect in Ableton Live, with a patch called “Add some random.” Place this MIDI effect onto the channel that you want to randomize.

Percent volume increase to decibels
VLC's volume to dB curve is not linear. If you increased it from 100% to 110%, that is a change of +2.5 dB.
Source: I also wanted to know the dB for a given percent level, so I measured it:
