Apple Lossless FLAC Converter is a simple-to-use software program that enables you to encode M4A files into FLAC format. It features advanced settings that can be easily configured in just a few steps.

The installation procedure takes little time to finish and does not require special attention. As far as the interface is concerned, Apple Lossless FLAC Converter opts for a classical window with a neatly organized structure, where audio tracks can be added to the task list using the file browser only, since the drag-and-drop method is not supported.

Batch processing is possible, which means that you can work with multiple items at the same time to speed up the entire task. You can specify the output directory and configure audio settings pertaining to the quality, sample rate, channel mode and codec. What's more, the PC can be scheduled to automatically power off on task completion.

We have not come across any problems in our tests, since Apple Lossless FLAC Converter did not hang, crash or pop up error messages. It carries out conversion jobs in reasonable time while remaining light on the system resources, so it does not affect the PC's overall performance. Since it can be minimized to the taskbar, it does not interrupt normal user activity either.

Its interface could used a complete redesign. On top of that, it does not include more advanced settings, considering that other similar apps offer the same functionality for free. Other than that, it serves its purpose and can be used by novices and those experienced alike for creating FLAC-formatted files from M4A audio tracks.
