HarmonyOS鸿蒙Next中frameSize是采样数还是字节数

OH_AudioStreamBuilder_SetFrameSizeInCallback(builder, 320); // 设置320，实际是640

设置320，实际回调640，设置640，实际回调1280。

/*
* Set the data frame size for each callback, use this function if the application requires a specific number
* of frames for processing.
* The frame size should be at least the size device process at one time, and less than half the internal
* buffer capacity.
*
* @since 11
*
* @param builder Reference provided by OH_AudioStreamBuilder_Create()
* @param frameSize The data frame size for each callback.
* @return AUDIOSTREAM_SUCCESS or an undesired error.
*/
OH_AudioStream_Result OH_AudioStreamBuilder_SetFrameSizeInCallback(OH_AudioStreamBuilder* builder,
int32_t frameSize);

请确认，frameSize是采样数还是字节数？
