Maximum bit rate in an audio frame is bps.
The characteristics of a decoded audio stream on the target device. The GUIDs for the compressed audio formats that are not supported by the HD audio class driver and can be implemented by third-party solutions are listed in the following table.
The GUIDs for the compressed audio formats ic are available as standard IEC encoded audio formats are listed in the following table. For a non-PCM format, these three members have been commandeered to store information about the compressed data in the audio stream.

Recommended for surround-sound standard definition movies. However, this structure is also not adequate in describing the stream for IEC transmissions because it was intended to iev a single set of characteristics and used for uncompressed, multi-channel PCM data.
Recommended for surround-sound high definition movies. Dolby Digital Plus supports content sample rates of 32 KHz, The characteristics of an encoded audio stream to be transmitted.

Based on the information in this structure, a user or an application might have difficulty inferring the quality level of the non-PCM stream. The new structure explicitly specifies the effective number of channels, sample size, and data rate of a non-PCM format. With the increase in iev storage devices that require compressed audio formats, applications must identify, describe, and use a variety of new encoded audio kec for transmitting content from PCs to devices such as HDMI or DisplayPort receiver.
The GUIDs for the compressed audio formats that are transmitted in high bit-rate audio sample packets are listed in the following table.
When Dolby Digital Plus content is transmitted over IECthe link-sampling rate must be four times the sampling rate of the content. To represent an encoded audio stream to be transmitted over an IEC compatible interface, an application must provide: Since Dolby MAT 2.
To represent an encoded audio stream to be transmitted over an IEC compatible interface, an application must provide:. With this information, an application can infer the quality level of the non-PCM stream after it is decompressed and played. Maximum rate in an audio frame is bps.
Recommended for over-the-air music and streaming.
