Today we launched the open source Auphonic Mobile App for Android – download it from the Google Play Store!

Some impressions:

It includes the same features as our Auphonic Mobile App for iOS:

• create audio and video recordings
• manage your productions and presets
• use all Auphonic algorithms directly from your Android devices (via the Auphonic API)

In contrast to the iOS version, on Android it's also possible to create productions from pre-existing local audio and video files!

At the moment the Auphonic Audio Recorder is supported for Android 4.0.3 or higher. If you have an older device, consider ...

Finally we found some time to collect a few listening examples for our audio algorithms – thanks to all the people who provided audio files!
Everything is processed automatically and you can try Auphonic yourself with the unprocessed files and will get the same results.

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!

Listen to the following examples with headphones to hear all details.

Global Loudness Normalization

Our Global Loudness Normalization Algorithms calculate the loudness of your audio and apply a ...

Getting started with podcasting can be a laborious process, because it costs time to produce and money to host a podcast.

At Auphonic, we are constantly trying to make this process simpler and cheaper, not just through our own free automatic audio post production web service, but also by offering tight integration with various third-party services.

In this article, we will show you how to set up a podcast in a few minutes for free. The final solution includes a blog with a feed from which your listener's can directly access your audio and video files, all hosted on ...

In case you have not noticed already, Auphonic now supports Amazon S3 and Archive.org as external services. Archive.org, also known as the 'Internet Archive', is a great service for publicly hosting audio and video files for free. Amazon S3, on the other hand, provides both free and affordable services for public or private file storage, featuring better download speeds and high durability. S3 also interfaces with Glacier, Amazon's cheap solution for long-term archiving and backups of data that does not require rapid access.

Similarly to our support for Dropbox, YouTube, Soundcloud, Libsyn, and FTP/SFTP, you can ...

Have you ever wondered how loud your audio productions should be? So have we, because it's a quite tricky question to answer!

On the one hand, you want to make sure your productions are loud enough. For example, they should still appear at a reasonable level in noisy environments (car, airplane, etc.), and their loudness should be comparable to that of other programs, no matter whether those are produced by yourself or by others.

On the other hand, you certainly don't want to compromise sound quality for sheer loudness. We have discussed in Audio loudness measurement and normalization ...

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! :)

About Libsyn

Liberated Syndication was one of the first podcast hosting services when ...

We are happy to launch Auphonic for iOS today. With the Auphonic Mobile App you can record audio or video and upload it to the Auphonic servers for post production. It further allows you to view, edit and manage your productions, presets and mobile recordings.

You can download the App from the Apple App Store.

We have also made our application open source. Feel free to report issues, send pull requests or just check out the source on GitHub: Auphonic Mobile.

There is a whole lot of things we have in store for mobile, especially the recorder will improve in ...

Do you want to process huge amounts of audio or video files in one single step?
That's why we built the new Auphonic Batch Production Interface!
It allows you to start multiple productions with an existing Preset and can be used for file-based, automated batch processing of audio file collections.

Step 1: Select Preset and Files

First you have to select multiple input files and one preset. A preset stores common metadata, output file formats, outgoing file transfers and algorithm settings for your productions. All input files will be processed with settings from the preset.

You can choose multiple ...

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
• for ...

We are very happy that Opus, an exciting new open audio codec, is now officially standardized by the Internet Engineering Task Force (IETF). Opus is particularly interesting for podcasts, radio books and internet audio in general due to its suitability for both, music and speech, and its outstanding sound quality at also very low bitrates.
In this article, we will listen to some examples of the Opus codec in action and have a closer look at the codec and how audio producers can benefit from it.

Why Opus?

Opus is a lossy audio codec that has some significant advantages over ...
