(There are other high-resolution files, which may be 24-bit and 88.1kHz or even 192kHz, but I’ll stick with 96 kHz, as that’s the highest sample rate that Macs can play. The majority of high-resolution files are 24-bit and 96kHz, which translates, roughly, into three times as much data per second as the audio you’ll find on a standard CD. That 44.1kHz means that there are 44,100 samples per second. The latter is the sample rate, or the number of samples per second this is the number of “frames,” as it were, of sound made in a second. The former is the “bit depth,” or the number of bits of data recorded for each sample the higher the better. To set up a surround (multichannel) speaker configuration, click Configure Speakers, then set up the configuration.CDs have audio at 16 bits and 44.1kHz. Drag the sliders to set the volume for each channel. If software volume control is available for your device, the Volume sliders appear blue to indicate that they’re active. You can also choose Enable or Disable from the menu, to keep the hardware sample rate converter turned on or off. The hardware sample rate converter is turned off if the input stream is encoded. When you choose Automatic from the pop-up menu, the hardware sample rate converter is turned on if the audio samples coming in are PCM and formatted according to the international standard IEC 60958-3. If your Mac supports the hardware sample rate converter, the Hardware Rate Converter pop-up menu is available in the Input pane. Make sure they match the appropriate settings for your audio device. In most cases, “Clock source” is set to the default.Ĭlick the Format pop-up menu, then set the sample rate and bit depth. On the right side of the Audio Devices window, choose the options available for the device you selected: You may be asked to unlock your device with a passcode or to trust the device.Ĭontrol-click the device, or click the Configure Selected Device pop-up menu at the bottom-left of the sidebar, then choose how the device is going to be used:įor sound input: Choose Use This Device for Sound Input.įor sound output: Choose Use This Device for Sound Output.įor playing system sounds: Choose Play Alerts and Sound Effects Through This Device.
