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 ...

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Some information here is outdated - please see the documentation of our new audio processing statistics and inspector instead: Auphonic Audio Inspector Help

As we have described last week in Chapter Marks for MP3, MP4 Audio and Vorbis Comment, chapter marks are a great way to make your podcasts more informative and searchable. But while chapters are incredibly convenient for listeners to have, they are also a lot of work for producers to create!

At Auphonic, we therefore offer several features to import chapters from your favourite audio editors and other sources, that make the creation of chapter marks much easier. Choose your option:

  1. Add Chapter Marks through the Web Interface
  2. Add Chapter Marks while Recording with our Mobile App
  3. Import ...

Do you know what's great about text? It's really easy to find stuff! You just do a quick search on that website you bookmarked last week, and boom! – there is the name of that book that you had read about, but whose title you had forgotten. But on the downside, text is not always the best medium to consume information, for example while you are driving a car. That's why we like podcasts: you can listen to them while you are driving, walking, exercising, etc. Podcasts keep your hands free and your eyes on the environment around you.

The official Auphonic Audio Example page is here: Audio Examples.
We will extend this page with further examples, so let us know if you have some great ones!

Podcast hosting is difficult: you have to create an RSS feed, a webpage and you must be able to serve audio files to a huge number of clients on your release date.
That's why we integrated the popular podcast hoster Libsyn (Liberated Syndication) as an external service in Auphonic. It's a great tool for file hosting and automatic RSS feed generation after processing and encoding your productions with Auphonic – you can even record your podcast with the Auphonic App and publish it with Libsyn immediately! :)
