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 ...

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. Do not under ...

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 ...

Best volume setting for audio capturing

Gain-staging without meters… Turn your output device [in this case your phone] up gradually, turning down your listening levels as you do this to keep the sound comfortable. If you start to hear ...

Normalize waveform level in Audacity

There's a difference between Normalisation to absolute loudness & perceived loudness. Standard Normalisation is absolute. It will turn the track up until the highest single peak reaches 0dBFS [...

Why do relatively small but high-frequency pressure changes cause hearing loss, but large but slow pressure changes don't?

The ear has a "high-pass" filter removing very low frequencys. If you go very fast up or down the eardrum may rupture, but it will heal. If you go slower pressure is equalized through the ...

Difference between Level, Signal Strength, Amplitude and Volume?

In Hi-Fi audio circles, Professional audio circles, Amateur audio circles, and other places, these four terms simply do not have definitions that are distinct from each other. In a lot of situations ...

Temporary increase in signal/sound level/volume?

This is partly a mic-technique issue for the person talking and singing - they need to be a lot closer to the microphone than they currently are. Vocal microphones such as SM58 are designed for hand-...

Easy way to remove spikes for the audio of a video file?

Your first problem with mixing this is that you have the main dialogue source panned hard left. I suspect you have a lavalier or remote wireless mic on the left channel, and camera mic on the right. ...

USB sound card not detecting Shure mic

Computer microphone inputs, both the built-in kind and the external USB kind, are designed to be used with relatively high-output electret condenser microphones. But that dynamic mic (Shure SV100) is ...

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:

How can I eliminate sounds below a certain threshold?

I doubt you will get an acceptable result with a simple gate setup: while you may get rid of low volume breathing sounds, it will also chop away natural endings. Noise reduction plugins with noise ...

How to increase mixdown volume

You might want to apply compression to individual tracks, track groups (rhythm+bass) maybe even the whole mix. Compressor is widely used to narrow down dynamic range which, among other things, makes ...

Behringer x32 Out 1-16 levels

I think so, yes. Route both L and R to one matrix bus, and assign that to Out 1. That depends on how you provide a signal to the Out port: Out 1-16 is just the output assignment. You set the volume ...

What is the difference in controlling volume through the software application, the system, and hardware?

This is known as gain-staging. In a pro environment this is done by watching the meters at each stage, setting levels to give the highest signal without ever going near distortion (leaving headroom). ...

How to input noise values in dBFS for ffmpeg silence detect

The trouble is, there's no such thing as 'dB'… well, of course there is but dB on its own is a measure of relative loudness, not absolute. See https://en.wikipedia.org/wiki/Decibel#...

How loud should I design my music? Not for personal opinion, but for other people listening in

You should be using EBU R 128 to normalize your volume. Simply normalizing to peak decibels from full scale is not enough. If you can't use R 128 then it's pretty subjective, but I usually use -6dBFS ...

How to change volume of a .wav file in a mp3gain-like way?

Wav, afaik, has no equivalent soft-gain parameter. You could simply use Audacity to normalise to zero [so you have a level playing field], then again to -92.8dB... but -92.8 is going to be awfully ...

Do some dedicated sound cards have a "stronger" line-out signal than on-board chips?

There are sound cards with higher line out level, these are interfaces with a pro line out whose nominal level is + 4 dBu (compared to the -10 dBv of a consumer line out). That's around 1.2 V vs 0.3 V....
