The Android Audio preset converts your 3GA recordings into the optimal format for Android smartphones and tablets. While modern Android devices technically support 3GA playback through the 3GPP decoder, many file managers, music players, and share dialogs do not recognize the .3ga extension or display it correctly in the UI. The Android Audio preset produces an M4A file (MPEG-4 audio) encoded with AAC-LC at 192 kbps and 44.1 kHz, which is the gold standard for Android audio compatibility guaranteed by Google's Compatibility Definition Document.
This preset was designed by analyzing Android's MediaCodec API documentation and the audio formats that Google guarantees will play on every Android device from version 3.1 (Honeycomb) onward. AAC in M4A is supported by YouTube Music, Samsung Music, Poweramp, and every other popular Android music player. The result is a file that plays flawlessly, appears with correct metadata in music apps, and integrates with Android's share and Chromecast features without any compatibility issues.
Even though 3GA originated on Android phones from Samsung and LG, the format was specific to certain manufacturer voice recorder apps and is not well-supported across the broader Android ecosystem. Converting to the Android Audio preset ensures your recordings work perfectly in Samsung Music, Google Files, YouTube Music, and any other Android application that plays audio. The .m4a extension is universally recognized and displayed correctly in file browsers on every Android skin.
The 192 kbps AAC bitrate is deliberately chosen to balance quality and file size on mobile devices. It exceeds the threshold for transparent audio quality with speech content from AMR sources, while remaining efficient enough for phones with limited storage. The output files are small enough to share via messaging apps like WhatsApp, Telegram, and Signal without hitting attachment size limits. Notifications and ringtone settings on Android also accept M4A/AAC files natively.
The Android Audio preset encodes to AAC-LC (Low Complexity) at 192 kbps with a 44.1 kHz sample rate in an M4A (MPEG-4 Part 14) container. AAC-LC is the audio codec that Android's Compatibility Definition Document (CDD) mandates all certified Android devices must support. The encoder uses two-channel stereo output with a constant bitrate for consistent streaming behavior. This configuration is compatible with Android 3.1+ (API level 12+), covering virtually every Android device in active use today.
At 192 kbps AAC, the output substantially exceeds the quality ceiling of the AMR source material. AMR-NB voice recordings from 3G-era phones are limited to 3.4 kHz bandwidth, so the AAC encoder has more than enough headroom to represent the decoded audio transparently. You could use 64 kbps AAC and still get transparent quality for this source material, but 192 kbps was chosen for the preset because it also handles higher-quality sources. The output sounds identical to the original 3GA recording.

The Android Audio preset is the simplest way to modernize old 3GA recordings for the Android ecosystem. The output M4A/AAC file plays in every Android app, displays correctly in file managers, and shares easily through messaging apps — solving all the compatibility quirks of the legacy 3GA format.
