Process audio files using SoX
Waveform
With the Jasny\Audio\Waveform class you can create a waveform as PNG like:
$waveform = new Waveform($filename, $options); $waveform->output();
Alternatively you can request a set of samples. This can be used to set draw a waveform in JavaScript (see waveform.js).
Options
Track statistics
$track = new Track($filename); $track->getStats();
{ channels: "1", dc_offset: "0.000016", min_level: "-0.162134", max_level: "0.153157", pk_lev: "-15.80", rms_lev: "-33.56", rms_pk: "-24.31", rms_tr: "-55.44", crest_factor: "7.72", flat_factor: "0.00", pk_count: "2", bit_depth: "30/32", length: "1.935601", scale_max: "1.000000", window: "0.050", samples: "42680", scaled_by: "2147483647.0", maximum_amplitude: "0.153157", minimum_amplitude: "-0.162134", midline_amplitude: "-0.004489", mean_norm: "0.010709", mean_amplitude: "0.000016", rms_amplitude: "0.020990", maximum_delta: "0.115579", minimum_delta: "0.000000", mean_delta: "0.003656", rms_delta: "0.008325", rough_frequency: "1391", volume_adjustment: "6.168", sample_rate: "22050" }
Convert track
