Setting Up Preferences.
During playback: Choose to have the window automatically scroll continuously or scroll page-by-page to keep the green playback marker visible when it reaches the right window edge. You can still scroll manually to other parts of the waveform. Choose "Do nothing" to prevent the window from scrolling automatically.
Scroll wheel: Check this option to enable scroll-zoom using the trackpad (gestures) or mouse.
Automatically check for app updates: This checkbox is available if you buy the app directly from us. For the Mac App Store version of Sound Studio, you will not see this checkbox because software updates are made directly through the Mac App Store.
Set default stereo bit rate, sample rate, sample size, and horizontal scale (zoom) of newly opened and created documents.
At startup create a new window: Check this box to automatically create a new, empty document with the default settings you've set above when there are no other files open.
You can customize the colors used to draw the main waveform views, markers, and grid. The colors can also be reset to the factory defaults.
Input controls the audio recording or capture hardware. Output controls the audio playback hardware.
By default, Sound Studio uses the audio input and output hardware selections from the System Preferences. You can specify that Sound Studio use a specific hardware device for input and another for output. The "1" and "2" options allow you to select which channels—left or right—are being used for input and output.
Most computers have built-in audio hardware, and this would show up as "System default" audio. If you have installed or plugged in some other audio hardware, such as a USB or FireWire audio device, you can select it in the preferences. The selection here only affects Sound Studio, so you can have Sound Studio play audio to one device while other applications play audio on another device.
Monitor playthrough input to output: Turning this on will preview the audio on the inputs by playing input audio on the audio outputs. You can get feedback (usually a screeching noise) if the speakers and microphones are too close or pointed at each other. Playthrough is useful for listening while recording your audio, to make sure you have the levels and connections set up properly.
Open Audio MIDI Setup: The Apple-supplied application “Audio MIDI Setup” is used to configure audio hardware connected to your computer. Use it to set the native sample rate and format of the hardware, in case you want to record at a higher than normal sample rate. Sound Studio will continue to work when there is a mismatch between the hardware sample rate and the file sample rate, by resampling the audio.
