X-Cube-Audio : Does the STM32L series support the hi-fi audio

[HungKai.Chien]

​Could we create a hi-fi audio project base on STM32L series?

What series can be used?​

[Javier1]

never used X-Cube-Audio, but in the software descrition says:

The X-CUBE-AUDIO package contains a comprehensive set of audio processing components for the STM32F4 and STM32F7 Series of microcontrollers

So only f4 and f7 microcontrollers are suported by this fw package

.....

Each audio effect application in X-CUBE-AUDIO expects a 16-bit stereo audio input signal at a 48-kHz sampling rate, using wave format with I/O data buffers dimensioned for 10 ms.

What does HI-fi means for you?

(audio rates of 32-bit/384 kHz)? way above the X-Cube_adio specs

You need to tell more about your project, but it looks like you got the wrong chip family.

Hi Javier,

The audio rate is 24 bits and 96K Hz.

The X-Cube-Audio release node has the following massage:

The playback support 24 bits and 96KHz, but we don’t know if the full series of MCUs supports.

[Javier1]

im a bit confused, are you mixing software packages?

• The USB device streaming , that seem the one youre taking the captures from?
• X-Cube-Audio clearly says only chips from families f4 and f7 supported.

By the way, UM1995 section 4:

CDC libraries are built to run either on a Cortex® M4 or on a Cortex® M7 core, without FPU usage. They can be integrated and run on corresponding STM32F4/STM32L4 or STM32F7 family devices. There is no other hardware dependency.
