Today we release three ideas to handle Auphonic Credits more flexible:

After more than two years of free Auphonic, we have to introduce our long promised freemium plans because of financial reasons.

Good news first: Auphonic is free for 2 hours of monthly processed audio!
If you need more, you can buy Recurring Credits (billed every month) or additional One-Time Credits (billed only once, added on top of free/recurring credits). We hope that this combination is affordable and allows many use cases, from small podcasters to big corporations.

Our Noise and Hum Reduction algorithms are now included in the Auphonic Leveler Batch Processor, version 1.2, on Windows and Mac. Note that this is a free update!

Auphonic Noise and Hum Reduction

The Auphonic Noise Reduction algorithms remove broadband background noise in audio files with slowly varying backgrounds.
First the audio file is segmented in regions with different background noise characteristics, then a noise print is extracted in each region and removed from the audio signal. A classifier decides if and how much noise reduction is necessary.
For more details and audio examples see Noise Reduction. ...

A few days ago a discussion in the Freak Show podcast pointed to an interesting BBC research project to render audio waveforms in the browser.
We now added a new output file format (Waveform Data File), which is generated by the open source tool audiowaveform and can be used to display interactive audio waveform data using the Peaks.js java script library. Here is an example screenshot:

The tool includes features to zoom in waveforms, to mark segments in audio files (could be interesting for chapter marks) and can be easily integrated ...
