A few days ago we added audio processing statistics to Auphonic productions, which display details about what our algorithms are changing in your audio file.
Some classifier results and processing steps are also shown directly in the player audio waveform and all statistics can be exported via the Auphonic API or the new output file format Audio Processing Statistics.
This article explains how to use and interpret the Auphonic Audio Processing Statistics.

UPDATE 2017:
Some information here is outdated - please see the documentation of our new audio processing statistics and inspector instead: Auphonic Audio Inspector Help

We are very proud to release version one of the Auphonic audio post processing web API. This is a complete REST API to all our algorithms and functionality, for example:

• audio loudness normalization to new loudness standards (EBU R128, ATSC A/85 and more)
• intelligent leveler, which balances levels between speakers, music and speech and applies compression as needed
• audio restoration algorithms, e.g. our automatic noise reduction classifies segments with different backgrounds and automatically removes noise and hum
• audio and video encoding to all common formats, metadata management
• automatic content deployment via Dropbox, FTP, SFTP, HTTP, YouTube, SoundCloud ...
