Recording settings in Logic Pro for iPad

You can use Recording settings to determine how Logic Pro for iPad responds while in record mode.

Audio recording

The following settings determine the file type and bit depth of newly recorded audio files. You can change those settings in an existing project if needed, and all new audio files are then created in that format without altering any previously recorded audio files in that project.

File Type pop-up menu: Select the audio file format for recording.
- AIFF: Audio file format mainly used on the Mac platform.
- WAVE (BWF): Most compatible audio file format.
- CAF: Allows for exceptionally long recordings if you plan on recording continuous, half-day or longer audio files.

Bit Depth pop-up menu: Set the bit depth for newly recorded audio files. A higher bit depth has the ability to capture a wider dynamic range.
Note: Choose the recording bit depth in Logic Pro to match the bit depth of your audio device. Each audio device either has a fixed bit depth or lets you choose a specific bit depth to send its digital audio signal to Logic Pro.
- 16-bit: Use only if you want to keep audio file sizes small or if your audio device supports 16-bit. Because 16-bit audio files only have a dynamic range of 96 dB (without dithering), they produce quantization distortion at very low signal levels.
- 24-bit: The most commonly used bit depth. Its file size is 50 percent larger than 16-bit audio files, but it has a better dynamic range of 144 dB with virtually no quantization distortion.
  With proper external gain staging, 24-bit is sufficient for any acoustic recording because the dynamic range of even the best microphone doesn’t exceed 140 dB.
- 32-bit float: Uses 32-bit floating point calculations to create audio files 33 percent larger than 24-bit audio files.
Tip: The advantage of using 32-bit float for recording is that you can remove digital clipping that occurred during the recording simply by lowering the gain of the audio region. You can also increase the gain of recordings with levels that are too low without increasing the noise floor.

Overlapping MIDI recordings

This setting determines the behavior when recording over existing MIDI regions. You can choose from two options, independently, when Cycle mode is turned on or off during recording:

Create Take Folder: A new take folder is created containing the existing MIDI region and a MIDI region for each cycle repetition. See Intro to takes.
Merge: Merges newly recorded MIDI data with the existing MIDI data in the same MIDI region. The region extends the length of the existing MIDI region when recording beyond its boundaries.

Important: The Overlapping MIDI Recordings settings are ignored when the Replace button is enabled in the control bar. In Replace mode, any existing MIDI data is overwritten.
