USB Audio driver USB 1.1 / 2.0 / 3.0

Ploytec's Windows USB Audio driver and Mac OS X USB Audio HAL-plugin driver enable buffersizes down to 32 samples (0.73 ms) and create an ultra highspeed USB audio connection, bypassing the operating system's audio, its mixing and samplerate conversion.

The commercial version of the USB Audio driver supports Alesis USB mixing desks, ART USB, Audiotrak EX / EX5 / Maya 5.1 USB (48kHz only), Audiotrak EX7 / Maya 7.1 USB, Audiotrak OPTOPlay, Creative Audigy 2 NX (48kHz only / Windows only), Creative Extigy (48kHz only), Creative MP3+ (48kHz only), Creative SoundBlaster Live 24bit external, Digidesign Mbox, Elektor USB audio, Event EZBus, Edirol. In the Structure area below, enable the Use option next to the driver used by the USB microphone (USB Audio CODEC, for example). Enable the Clock option next to that device and click on Done.

This not only gives you low latencies, but better sound quality also.

You can use Audio MIDI Setup to configure audio input and output devices that you use with your iMac, such as microphones and multichannel audio interfaces. Audio MIDI Setup works with many types of audio and MIDI interface devices, including your computer’s built-in audio and digital multichannel audio devices. It works with devices connected to your iMac using FireWire, USB, Bluetooth, PCMCIA, and PCI.

The settings you can change in Audio MIDI Setup depend on the audio device you’re using. For example, if the device supports volume control, you can adjust the volume for each channel your audio output device has available by following these steps:

1. Connect your audio devices to your iMac. If necessary, install any software included with the devices. See the documentation that came with your audio devices.
2. Open Audio MIDI Setup (you can find it in Utilities, inside your computer's Applications folder).
3. Choose an audio device from the list on the left side of the Audio Devices window.
   • To use the device for sound input, choose 'Use this device for sound input' from the Action pop-up menu.
   • To use the device for sound output, choose 'Use this device for sound output' from the Action pop-up menu. If you also want to use the device to play system sounds, choose 'Play alerts and sound effects through this device' from the Action pop-up menu.
4. On the right side of the Audio Devices window, choose the options available for the device you're setting up:
   • In most cases, leave the 'Clock source' pop-up menu on the default setting.
   • To set up surround (multichannel) speaker configurations, click Configure Speakers. Then, choose the type of configuration you want to use. See Set up external speakers for stereo or surround sound for more information.
   • You can set the sample rate and bit depth in the Format pop-up menus. Make sure they match the appropriate settings for your audio device and that the input and output sample rates are set to the same value. For example, the built-in speakers of an iMac computer may appear like this:

Additional settings

• If your iMac supports the hardware sample rate converter, the Hardware Rate Converter pop-up menu is available in the Input menu. 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. The hardware sample rate converter is turned off if the input stream is encoded. You can also choose Enable or Disable from the menu to keep the hardware sample rate converter turned on or off.
  If you choose Enable from the menu, you may not be able to stream non-LPCM or encoded audio because the audio may not be recognized.
• If software volume control is available for your device, the Volume sliders are blue to indicate they are active. Drag the sliders to set the volume for each channel.
