QUESTION

Why is the volume coming from -80db to 0 - not even starting at 0?

Asked 2021-Jun-23 at 18:06

I'm very new to sound. I've never explored this area in my whole life.

I thought decibels was a measure starting at 0. But in Unity, it starts at -80db and and "0db" it seems it's the "100%" level volume.

Moreover, when I change the sound to -40db it's not "half-way" between -80db and and 0 it seems it's much closer to -80db. So the user hears nothing when it's "half-way":

I couldn't find anywhere how to setup sound properly, and how to make the user choose "properly" the sound (= good scale).

Any idea / Unity valuable sample for this?

From Wikipedia -> Decibel

dB is a relative unit of measurement [...] It expresses the ratio of two values

This is very common for Audio Mixers and Amps that 0 means 100% of the configured Pre-Gain (-> in this case the input volume of your individual AudioSources).

Why? -> The given dB are just the additional "multiplicator" (as said it is a logarithmic ratio between two values).

Usually as an Audio manager you first configure all Pre-Gains in a way that basically everything has more or less the same absolute volume if all mixer sliders are at 0.

Then you start to actually mix them according to your needs and only move certain volumes up or down to increase or decrease the volume by a certain factor. (Except for fading it is usually pretty uncommon to actually pull a slider down to the minimum - usually you rather Mute the channel)

0dB just means 1:1 => Don't change.
e.g. 6dB means about 2:1 => twice as loud as the input volume
e.g. -6dB means about 1:2 => half as loud as the input volume
e.g. 20dB means about 10:1 => Ten times as loud as the input volume
e.g. -80dB means 1:10000 => So 0.0001 of the input volume

So the -80 is chosen a little bit arbitrary .. it could as well be -60 (=>factor of 0.001) or -100 (=> factor of 0.00001). "It doesn't really matter!". At a certain point the volume is simply so low that you won't hear it anymore depending on what the default maximum output of your Amp is and how precise you need the output to be.

You can e.g. use this dB calculator to check what dB value results in what actual factor.

For a better explanation of the dB measure itself see also e.g. these posts and What's the minimum decibel value?

QUESTION

How to perform retrigger/restart sample in gstreamer without cutting the previous playback

Asked 2021-May-19 at 07:44

So I am trying to make a drum machine with gstreamer. For those who are not familiar with a drum machine have a look at:

https://www.youtube.com/watch?v=KC7UaUD5rEA

Basically you have a specific sample loaded to a track. Each track has 16 steps which you can enable or disable. When you press play the drum machine will loop over the steps and when a step is enabled it will play that sound.

I put the pipeline in play state and each step I perform a seek_simple back to the start of the pipeline. To trigger the sound I mute and demute the wav each step according to the wanted rhythm/pattern.

The issue: By performing the seek back to the start the tail of the wav sample/sound is cut off and this makes a choppy sound. Ideally I'd like to re-trigger a wav sample but the previous one should continue to play until done.

The question: How can I re trigger a sound without cutting of it's tail?

Ps: I've tried to play with the seek flags "flush", "keep_unit", ... but without success.

My loop:

I managed to achieve my goal by using this C library: https://soundprogramming.net/programming/tutorial-using-sdl2-and-sdl_mixer-to-play-samples/

This example gives a way to play multiple sound simultaneously. I then made a python wrapper around it and push a wav file to it. Follow this tutorial:

Feel free to post the gstreamer solution.

In Unity, I have made a working slider for volume that keeps it's value upon scene change. When the game is built, it no longer saves the value

Asked 2021-Feb-24 at 02:53

I'm really new to using Unity and C#, I'll do my best to explain the situation and show relevant code.

So basically I am creating a Settings Menu in my game. Options I have are a fullscreen toggle, resolution dropdown, graphics dropdown and volume slider. All of these settings will maintain the selection on a scene change or the game being shutdown and run again, other than the volume slider.

In Unity, the volume slider will maintain it's selection. Just not in the game once it has been built. It will instead default back to middle of the slider.

Here is relevant code.

Your problem has nothing to do with SerializeField. Are you aware what SerializeField do? SerializeField in Unity used for reflecting object value to Unity Editor Inspector. It doesn't affect variable protection level. When you didn't assign any protection accessors (private, public, internal), it is private as default. So only accesible in this class level. If you want to access it from another class, you should just add public accessor.

The sfx is not playing and I want that when I change the sfx slider it will sound the sfx effect for a short time so each time I change the slider value it will play the sfx to hear the volume of it.

For duplicates, it's a known problem: the problem is on standalone where it appears to duplicate each resolution with refresh rates of 60Hz and 48Hz.

For example: 640x480@48Hz; 640x480@60Hz; etc

A solution could be a Linq statement, selecting only 60Hz frequencies (or 48Hz):
