Select [ON] to record audio in 32-bit float format. 32-bit float format allows recording across a wide dynamic range with reduced noise at low volumes and distortion at high volumes. By using applications or software that support 32-bit float format to adjust to the appropriate volume, you can reduce noise at low volumes and distortion at high volumes, allowing for a clearer sound in post-production regardless of the settings during recording. You can increase the volume without noticeable noise and decrease the volume without worrying about audio distortion at high volumes.
- 32-bit float audio recording can be performed when one of the following is selected for [Video file type] in the video recording menu.
- [N-RAW 12-bit (NEV)]
- [R3D NE 12-bit (R3D)]
- [ProRes RAW HQ 12-bit (MOV)]
- [ProRes 422 HQ 10-bit (MOV)]
- [H.265 10-bit (MOV)]
- [H.265 8-bit (MOV)]
- [AUTO] cannot be selected for [Audio input sensitivity] in the video recording menu during 32-bit float audio recording.
Cautions: 32-bit float audio recording
- When performing 32-bit float audio recording, [Audio input sensitivity] cannot be changed during video recording.
- Audio recorded using 32-bit float format may not be played back properly depending on the operating system or model of your smart device or computer.
- There may be audio distortion or the volume may be too low when played back using applications or software that cannot adjust audio levels.
- 32-bit float audio recording is a recording format that reduces the occurrence of noise and audio distortion during audio signal processing. Noises and audio distortion arising within audio input devices such as external microphones, as well as noises produced by air conditioning systems, etc., will be recorded.
