Thanks to the great feedback of our users in the Auphonic Goes Freemium blog post, in private emails and in other articles, we got many ideas what should be changed and can be added to our recently introduced freemium model.

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

• Let your podcast listeners Donate Credits directly to your Auphonic account to support the audio post production of your show.
• Transfer One-Time Credits to another Auphonic account.
• Refund Credits of a production if you are not satisfied with our results or if something went wrong.

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.

Here are all plans: Auphonic Pricing

Last week we presented our new multitrack algorithms at the Podlove Podcaster Workshop in Berlin. Lot's of users asked us about a multitrack version of our system before - now it's here and can be used!
We reworked all our algorithms and therefore start with a private beta program for our long-term users and supporters.

What is Multitrack?

Auphonic is optimized to process stereo or mono audio files of a final mix. However, many recordings consist ...

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.

Our Hum ...

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 in HTML 5 audio or video players.

Here you can try a working demo example by BBC:

Auphonic Waveform Data Output File

To create a waveform display in browsers using Peak.js, you need a data file with the audio information. Now this can be done with Auphonic by adding the output file format Waveform Data file to your production:

You can also use the open source tool audiowaveform to calculate the waveform data yourself.

Two years ago, at March 27 in 2012, we released the Auphonic web service for the general public. It all started with an interview in Der Lautsprecher by Tim Pritlove (German only) at the first Podlove developer meeting and a lot happened since then.

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.
