GetAudioGain
GetAudioGain is a tool that will help you obtain the gain values of an audio file, separating it into segments based on a specified time lapse, as well as knowing which parts of the audio can be considered silence.
Instalation
You can install this tool in your projects this way
npm install get-audio-gain
OR
yarn add get-audio-gain
Usage
To use this tool, first of all, we need to import it into our project
const getAudioGain = require("get-audio-gain");
Now we will be able to use the function
You must pass as a parameter the path of your audio file
Example:
getAudioGain("audio-example.wav").then(console.log).catch(console.error);
You will get a result like this:
[
{
"segment":0,
"gainAvg":99.21582456458636,
"silence":false
},
{
"segment":1,
"gainAvg":124.71142507256894,
"silence":false
},
{
"segment":2,
"gainAvg":65.4035286647315,
"silence":true
},
{
"segment":3,
"gainAvg":117.08377177068215,
"silence":false
}
...
Response description
segment:
Single segment of the current reading, determined by the lapse parameter. For example, if the specified time is 250 milliseconds, segment 0 represents reading from 0 to 250 milliseconds, and segment 1 from 250 to 500, etc.
gainAvg
Represent the gain average for each segment
silence
Define if the segment can be considered silence, according to the parameter threshold If the specified threshold is 74 and average gain is less than 74, silence will be true
Parameters definition
| Parameter | Description | Type | Optional | Default | | --------- | ------------------------------------------------------------- | ------ | -------- | ------- | | filePath | Audio file path | string | false | N/A | | lapse | Time lapse for each segment in milliseconds | number | true | 250 | | threshold | threshold to define what is a silence or a considerable sound | number | true | 110 |
Usage example with optional parameters
getAudioGain("audio-file.wav", 200, 80);
