Then in v10.5.7, AppleUSBAudio’s engine model was redesigned to combine multiple streams per engine when possible.

In Mac OS v10.5.6 and earlier, AppleUSBAudio restricted each engine to one stream only. One or more streams are associated with each engine. Example: 10 channels of input and 10 channels of output, 32-bit 192 kHzĪppleUSBAudio represents the streams of a USB audio device to the application layer using IOAudioFamily's IOAudioStream entities. High speed isochronous audio data transfersĬan support high channel count/sample rates. Input adaptive endpoints are not supported.ĭevice informs host of volume, mute, input selector, clock validityĬlock Source, Clock Selector, Clock Multiplier Usually paired with an asynchronous input endpoint. Streams must meet requirements to occupy the same engine Input stream sample synchronous to output stream The same follows for the “USB Audio 2.0” column. A checkmark in the “USB Audio 1.0” column means that this feature is supported for USB Audio 1.0 devices. Table 2 Supported features in AppleUSBAudio.
Table 2 highlights some of the supported features that are discussed in this article.

Please see the Audio Device Driver Programming Guide for more details.ĪppleUSBAudio is a mature driver that supports many USB Audio 1.0 and 2.0 features. AppleUSBAudio builds upon the IOAudioFamily layer which provides general audio driver functions like maintaining the sample and mix buffers, facilitating communication over the kernel and user space boundary through user clients, and more. The AppleUSBAudio driver communicates to devices via the USB transport, using the IOUSBFamily APIs.

In addition to transporting audio data between the hardware and the host’s sample buffer, it also communicates format and control changes between the host and the device (like volume, mute, format, input/clock source, etc.) AppleUSBAudio presents these hardware resources to applications through the HAL (audio hardware abstraction layer.)

There are close to a hundred creators just like you to help you out.AppleUSBAudio is an I/O Kit based kernel driver that is designed to support both USB Audio 1.0 and USB Audio 2.0 class compliant devices. You may also find that tweaking specific settings on your hardware devices improves your output. You may find that turning on some of Zoom's processing makes your sound quality better. Close unused apps or browser tabs when you’re delivering a music performance on Zoom, this will free up your computer’s processing powerĭue to the variety of audio input hardware that exists, the same settings will not work for all cases.This is because the connection of multiple audio devices drains your battery rather quickly Your device (laptop/iPad/phone) must be fully charged or plugged in port during the session.The Internet is the primary requirement and an important factor during a zoom session.Zoom allows you to optimize audio with the above mentioned controls only on your desktop app, thus ensure as a performer you’re always using your Laptop.
