New Output Format to Render Audio Waveforms in the Browser

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.

How to Import Chapter Marks in Auphonic

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

Chapter Marks for MP3, MP4 Audio and Vorbis Comment (Enhanced Podcasts)

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 ...
