Sorry, doesn't work at all - images empty or rubbish

Hi, tried your code but no luck to get some decent results. Tried different types/length of wave files and see nothing useful.

• Produces HTML files however see nothing, bunch of spans inside the HTML
• Produces SVG files however errors in the SVG's, doesn't look like a wave.
• Produces PNG files however only a background or empty.

Using PHP 5.4.16 (cli), set error_reporting( E_ALL ) and no warnings etc at all. What is going on?

Update, test it with latest PHP7:

Many messages like these when error_reporting( E_ALL ): Notice: A non well formed numeric value encountered in Waveform\Generator\Svg.php on line 93 PHP Notice: A non well formed numeric value encountered in Waveform\Generator\Svg.php on line 93
