In the past few years, we have covered plenty of awesome audio players and audio friendly themes. WaveSurfer for WordPress is also worth a look. It is an audio player capable of displaying waveforms with a mix of different audio channels. It supports mp3, m4a and other audio formats supported by WordPress.
You can change colors, height, weight, and button attributes for your shortcodes. If you decide to deactivate the plugin, the shortcode uses the default audio player. You can download this plugin for free.
