Simple PHP Library for working with wav-files
Installation using composer composer require nkolosov/wav
#Usage Simple usage:
...
$file = Parser::fromFile('/path/to/file.wav');
echo $file->getSampleRate(); //44100
...You can create music file from code:
...
$sampleBuilder = new Piano(); //create piano sound generator
//generate first notes of Für Elise (Ludwig van Beethoven)
$samples = [
$sampleBuilder->note('E', 5, 0.3),
$sampleBuilder->note('D#', 5, 0.3),
$sampleBuilder->note('E', 5, 0.3),
$sampleBuilder->note('D#', 5, 0.3),
$sampleBuilder->note('E', 5, 0.3),
$sampleBuilder->note('H', 4, 0.3),
$sampleBuilder->note('D', 5, 0.3),
$sampleBuilder->note('C', 5, 0.3),
$sampleBuilder->note('A', 4, 1),
];
$builder = (new Builder())
->setAudioFormat(\Wav\WaveFormat::PCM)
->setNumberOfChannels(1)
->setSampleRate(\Wav\Builder::DEFAULT_SAMPLE_RATE)
->setByteRate(\Wav\Builder::DEFAULT_SAMPLE_RATE * 1 * 16 / 8)
->setBlockAlign(1 * 16 / 8)
->setBitsPerSample(16)
->setSamples($samples);
$audio = $builder->build();
$audio->returnContent(); //return wav-file content directly to browser/console
