MicroAC for OS X - Streamlined, Batch Audio File Converter for 9 Formats

in OS X Development

[prMac.com] San Francisco, California - Independent developer Aaron Smith has announced MicroAC 1.1 for Mac OS X, an update to his streamlined audio application, which enables batch conversion between nine Core Audio compatible formats. Ideal for developers, audio engineers, and audiophiles, MicroAC is a GUI version of Apple's command line "afconvert" tool and comes with support for most of its input and output formats. Features include Drag and Drop, Concurrency Control, Queueing & Requeueing, Sample Rate Selection, and Multi-Channel Compatibility.

Feature Highlights:
* Drag and Drop Files - batch drag and drop audio files and folders for conversion
* Concurrency Control - choose the number of conversions that are processed concurrently (1- 10)
* Queueing & Requeueing - add, delete, start, and restart conversion of files
* Sample Rate Selection - select 22,050 kHz or 44,100 kHz sampling rate
* Channels - convert single or multi-channel audio files (1 - 7)

MicroAC puts the operating controls, queued files list, queue options, output format drop-down menus, destination for converted files, and other options in a single, well-organized window. Once the user selects the Start Queue button, individual files in the queued files list can display one of three conditions: completed, processing, or waiting to be processed. A queue option allows users to automatically delete completed files from the list. The Requeue button lets users select a completed file to convert again to a secondary format. Also user selectable is the number of files in the batch that are processed concurrently (1 - 10).

One of the Output Format drop-down menus displays the nine types of audio files the app can convert from or to: 3GP Audio, 3GP-2 Audio, AIFC, AIFF, Apple MPEG-4 Audio, Apple MPEG-4 AudioBooks, CAF, MPEG-4 Audio, and WAVE. Another menu displays alternative file extensions, such as .aiff or .aif when converting to the AIFF format. The last menu lets users select the specific data format they would like to opt for given their choice of audio file format. Also user-selectable are sample rate (22,050 or 44,100 kHz) and the number of channels (1 - 7) in multi-channel audio files.

* 3gp (.3gp)
aac, aace, aacf, aach, aacl, aacp
