Attention

The Auphonic Recorder includes no audio editor as implemented in Auphonic Edit for Android.
But you can use any other iOS audio editor and share the results with our App to export mobile audio from iOS to our Web Service!

Integrated Audio Recorder

The focus of the integrated recorder is robust and high-quality recording:
It is possible to choose between multiple microphones from your iPhone, an external USB interface, headsets, etc. and all default iOS pre-processing is deactivated to get the raw audio signal.

The recording interface displays the current maximum peak level, available recording time (storage), you can add and edit Chapter Markers and it’s possible to record in background while the screen is turned off.

The recorded signal is encoded in an uncompressed PCM (.caf) or compressed AAC format (Mono: 120kbps, Stereo: 160kbps), written to disk every audio buffer so that no data loss happens if the app gets killed. You can choose the recording Samplerate (44.1kHz, 48kHz or device default), Mono/Stereo and set the recording Precision/bit depth (16bit or 24bit).
It’s possible to lower the microphone Input Gain, if the recorded signal is too loud (peak level display is very high) or produces Clipping. Note that our default input gain setting is automatically adapted for various microphone types and should work in most situations.
Activate Monitoring to hear the audio signal during recording with headphones.

Note

For our compressed AAC format, we don’t use an MP4/M4A container, because it might get corrupted in the case of a crash.
We use the AAC ADTS format to always write a valid audio stream, even if the app gets killed.

In the Waveform View it’s possible to set start and stop markers (cuts start/end of your audio), to set metadata, Chapter Marks and to export and process the audio file using the Auphonic Web Service or share it with other iOS apps.
