A/B Audio Sync

Click here for a live demo

The A/B Audio Sync plugin for WordPress allows developers to queue two songs (WAV, MP3, any format the web browser can handle) and play one at a time, with a toggle switch between them. This gives users the ability to switch tracks quickly, without losing the track time, to hear differences in audio tracks.

This is great for demonstrating audio enhancement technology or production/post-production mixes or even the differences between audio format quality.
