Prepare the input channel for recording

When you enable recording for a track, the track can record from the Default Device channel specified in the Audio Hardware section of the Preferences dialog box. This dialog box includes the ASIO Settings button (Windows only), which you use to enable audio inputs connected to the computer. Submix and master tracks always receive audio from tracks within the sequence, so recording and track input options are unavailable for them.

 Choose Edit > Preferences > Audio Hardware (Windows) or Premiere Pro > Preferences > Audio Hardware (Mac OS), and set the following options:
Default Device
Determines which connected audio device is routed into and out of Adobe Premiere Pro. Select the ASIO drivers for the audio device. If the sound card doesn’t have manufacturer‑supplied ASIO drivers, choose Premiere Pro Windows Sound for this setting. For a device to be available, an up‑to‑date driver must be properly installed in Windows. In addition, if you want to input more than two stereo channels or monitor 5.1 surround audio, the device driver must comply with the ASIO (Audio Stream Input Output) specification. If it doesn’t, only stereo inputs and outputs will be available, regardless of the number of hardware inputs and outputs that are connected.

ASIO Settings (Windows only)
Specifies the ASIO settings for the selected device. The settings in this dialog box are set by the device and driver you use, not by Adobe Premiere Pro. See the documentation for the ASIO device and driver you use.

Buffersize (Mac OS only)
Specifies the size of the buffer, in kilobytes, that Adobe Premiere Pro uses for recording audio.
