README

This package solves a real-world problem related to converting an audio file into a useful waveform structure.

Installation

composer require omerkamcili/waveform-genarator

Usage example

Provide raw output txt file from an audio ffmpeg silence detection to channel.

In case for example you have a detected file like customer_channel.txt and it looks like;

customer_channel.txt

[silencedetect @ 0x7fbfbbc076a0] silence_start: 3.504
[silencedetect @ 0x7fbfbbc076a0] silence_end: 6.656 | silence_duration: 3.152
[silencedetect @ 0x7fbfbbc076a0] silence_start: 14
[silencedetect @ 0x7fbfbbc076a0] silence_end: 19.712 | silence_duration: 5.712
[silencedetect @ 0x7fbfbbc076a0] silence_start: 20.144
[silencedetect @ 0x7fbfbbc076a0] silence_end: 27.264 | silence_duration: 7.12
[silencedetect @ 0x7fbfbbc076a0] silence_start: 36.528
[silencedetect @ 0x7fbfbbc076a0] silence_end: 41.728 | silence_duration: 5.2
[silencedetect @ 0x7fbfbbc076a0] silence_start: 47.28
[silencedetect @ 0x7fbfbbc076a0] silence_end: 49.792 | silence_duration: 2.512

Create a channel and provide parameters (channel name, raw output from silence-detect)

$channel = new WaveformGenerator\Channels\FileChannel('customer_channel', 'customer_channel.txt');

Create FFMpeg parser (you are able to implement the other silence detectors if there is)

$parser = new WaveformGenerator\Parsers\FFMpegParser();

Create Converter instance and manage what do you need

$totalSessionTime = 73.42; // Total session time from meeting
$converter = new Converter($parser, $totalSessionTime);

Getting beautifully talk collections with talk percentage and longest monologue

$converter->getTalkCollections();

Getting just longest monologue from channel

$converter->getLongestMonologueFromChannel('customer_channel');

Getting just talks percentage from channel

$converter->getChannelTalkPercentage('customer_channel');
