How to Convert raw-audio to iPhone Audio?

  1. Click the “Choose Files” button to select your raw-audio files.
  2. Click the “Convert to iPhone Audio” button to start the conversion.
  3. When the status change to “Done” click the “Download iPhone Audio” button

Easy to Use

Simply upload your raw-audio files and click the convert button. You can also batch convert raw-audio to iPhone Audio format.

Best Quality

We use both open source and custom software to make sure our conversions are of the highest quality. In most cases, you can fine-tune conversion parameters using “Advanced Settings” (optional, look for the icon).

Free & Secure

Our raw-audio to iPhone Audio Converter is free and works on any web browser. We guarantee file security and privacy. Files are protected with 256-bit SSL encryption and automatically deleted after 8 hours.


Raw-audio is a headerless PCM sound file: nothing but the digital samples themselves, with no metadata, no compression, and no marker identifying where the audio begins. A WAV file is essentially the same data with a short descriptive header attached. Raw-audio appears most often as the output of audio hardware, DSP pipelines, and telephony systems, and as the intermediate stage between processing steps.

 

How to open a raw-audio file?

Import it into Audacity using File → Import → Raw Data. You will be asked for the encoding, byte order, channel count, and sample rate, since the file itself does not record them.

 

Common defaults are 16-bit signed PCM at 44,100 Hz or 48,000 Hz; telephony recordings are frequently 8-bit at 8,000 Hz. FFmpeg and SoX can play and convert raw-audio from the command line once you supply the same parameters. Save the result as WAV or MP3 so the settings travel with the file from then on. You can also convert the file with our RAW to MP3 tool.

 

Developed by: No single vendor — a generic PCM stream

Initial Release: N/A


iPhone Audio is an M4A file encoded for Apple iPhone, containing AAC audio in an MPEG-4 container. AAC delivers noticeably better sound than MP3 at the same bitrate, which is why Apple adopted it as the default for the iTunes Store and for music on iOS. Choosing this preset produces a file the iPhone plays natively, with artwork and track tags intact.

 

How to open an iPhone Audio file?

On the phone, the file plays straight away in the Music, Voice Memos, or Files app — nothing extra is required.

 

To get the file onto the device, sync it through iTunes, the Finder on macOS, or iCloud Drive. On a computer the same M4A opens in iTunes, the Apple Music app, Windows Media Player, VLC media player, and every major web browser. For maximum compatibility with older devices, convert it with our M4A to MP3 tool.
