Hi everyone,
I’m currently working on a project that involves spatial audio processing using the STARSS23 dataset. My goal is to convert the FOA (First-Order Ambisonics) format audio files from this dataset into a format compatible with a planar circular four-microphone array.

The planar circular microphone array I’m using has the following coordinates in spherical format:

Mic 1: (0°, 0°, 1)
Mic 2: (90°, 0°, 1)
Mic 3: (180°, 0°, 1)
Mic 4: (270°, 0°, 1)
I’ve read that spaudiopy is a powerful tool for such spatial audio processing tasks, and I believe it can help with this conversion. However, I’m looking for guidance on how to effectively decode FOA signals to match this specific planar circular microphone configuration.

If anyone has experience with this kind of conversion or can point me to relevant documentation or examples using spaudiopy, I would greatly appreciate your help.

Thanks in advance for your assistance!

Best regards
