The ibs parameter lacks documentation explaining why 512 bytes was chosen as the buffer size or how this value relates to the sample rate conversion requirements.

Suggested change
in_valid_bit_depth 32
in_valid_bit_depth 32
# ibs (input buffer size) set to 512 bytes.
# 512 bytes is a commonly used buffer size in audio processing, providing a balance between latency and CPU efficiency.
# For 32-bit samples at 48kHz, this allows for efficient block processing and aligns with typical hardware period sizes.
