Test assembly with STM32Cube Expansion USBAudioStreaming V1.0.0

Some efforts to adopt STMicroelectronics code of "USB Device Audio Streaming", which is an expansion software package for STM32Cube.

What I expect this software supports:

• Playback Audio
• Recording Audio
• Playback sampling rate: 96KHz (for hi-fi audio), 48KHz and 44.1KHz .
• Playback audio resolution: 24 bits (for hi-fi audio) and 16 bits.
• Playback synchronization using feedback.
• Recording synchronization using Implicit feedback(remove samples/decrease packet length).
• Recording sampling rate: 96KHz (for hi-fi audio) , 48KHz, 44.1KHz and 16KHz.
• Recording audio resolution: 24 bits for hi-fi audio) and 16 bits.
• Both recording and playback support many sampling rate, which may be fixed in compilation stage.
• Both recording and playback support multi-frequency: switch between sampling rate on runtime by host request.
• Both recording and playback support mute and volume control.

What I want from this software:

• Recording Audio
• Recording sampling rate: 96KHz (for hi-fi audio) , 48KHz, 44.1KHz and 16KHz.
• Recording audio resolution: 24 bits for hi-fi audio) and 16 bits.
