Navigation: Upper left corner click: Arena –> Preferences –> Audio
The audio tab presents you with options that control how audio should be output from Resolume.
Under Audio Output Device you can select the device that Resolume should use for audio output. If an ASIO device is selected, an extra button will be displayed that enables access to ASIO settings.
You can then select which channels should be used for the main output via Master Output Channels. If you are using an audio device that supports more than two channels, you can choose the channels used for monitoring the preview audio via Preview Output Channels.
Higher sample rates provide higher quality audio but will require more processing, especially if audio effects are in use. 48000 is a good choice.
Higher buffer sizes will introduce more latency into the system but setting the buffer size too low may cause glitches in the audio. 512 or 1024 are usually safe choices.
Similar to selecting the output device, here you can select which device Resolume uses for all incoming audio.
Under External Audio FFT Input you can the channels that should be used for external audio analysis. You can boost the gain if the signal is coming too low.
You can also set the FFT gain in the main interface via
View > Show FFT Gain
In Arena, you can select which channels to use for your source of SMPTE sync. SMPTE Timecode Input 1 and SMPTE Timecode Input 2 should both be set to SMPTE Timecode Input 1.
