New version 1.1 has been released

New version 1.1 of Audio Mastering for iPad already available in App Store. This is easy-to-use application with high-quality fully 24 bit audio processing algorithms. The perfect way to make your songs a little better.

Feature of this version:

• Function Normalize at conversion of file. 
• Feature "Open in" that give possibility "Open audio file in Audio Mastering" from other applications (like AudioShare, Mail, etc).
• Export audio file directly to AudioShare application.
• Playback from Mark In position when selecting file.
• Files .m4a are supported now (you need to reload file).
• Built-in description updated.
• Some minor bugs fixed.

Are you thinking iPad is not good enough for audio mastering? For better sound use external DAC and quality monitors. High-quality audio processing is already in this application.

What's new:

• Function Normalize at conversion of file. 
• Feature "Open in" that give possibility "Open audio file in Audio Mastering" from other applications (like AudioShare, Mail, etc).
• Export audio file directly to AudioShare application.
• Playback from Mark In position when selecting file.

• Built-in description updated.
• Some minor bugs fixed.

Detailed review of purpose and features

It is the most complete review of the purpose and features of Audio Mastering for iPad from Music App Blog. I recommend it to everyone who wants to know the main purpose of this application.

Music App Review - Audio Mastering for iPad

... "As explained by Bob Katz (one of the most respected mastering engineers in the world) in his excellent book on the subject, mastering is both an art and a science. It can also involve a whole range of different audio processing options. It would perhaps be unfair to expect a $9.99 app to cover all the possibilities but Audio Mastering manages to pack in a decent suite of tools given the iOS format and the price."

What to expect in the next versions

So, everyone is interested to know what else in this app will be. Also, there is already the most requested features. My prediction for the next two versions.

The nearest version 1.1 (will submit in a few days)

• Function Normalize at conversion of file.
• Feature "Open in" that give possibility "Open audio file in Audio Mastering" from other applications. As example from AudioShare app.
• Export audio file directly to AudioShare application.
• Some bugs fixed (it's main reason of this release).

Next version 1.2 (in a two-three weeks)

• Recording to file from external source.
• Support AudioBus as external source.
• Convert sample rate from 96, 88.2, 44.1 to 48 kHz.
• Solo mode for Equalizer bands.

I'm working on it!

Feedback

The fully functional audio mastering application with professional quality delivers an unprecedented level of clarity, punch and warmth to your mix. Precise control of all parameters and highest quality audio processing, the most important part of any mastering, is the base of this application.

This all-in-one tool gives you all the features you need to add the finishing touch of magic to your music. Also with Audio Mastering you can convert audio formats, change sample rate, convert bit depth, record a track, cut part of track and apply fade-in and fade-outs.

Support for Inter-App audio and Audiobus allows you to use Audio Mastering together with other music applications. Moreover, with an external audio interface, you can use this application as a powerful sound processor with 32 bit / 96 kHz processing in your studio and integrate it with other studio equipment.

The easy-to-use interface lets you tweak all the controls in real time while auditioning the result as you make parameter adjustments. Using a unique feature - two different control modes - you can quickly and easily adjust the final mix in basic mode, or fine-tune the settings in more details for the best possible sound in advanced mode. Includes built-in presets that allow you to quickly find a suitable starting point for your music and then tweak the processing to get a desired result.
