Before you begin​

  • Confirm the exact product variant and the firmware mode (USB or I2S) the device is running.
  • Check the current firmware version before applying version-specific steps.
  • Answers on this page were last verified on 2026-09-01; re-check the linked official sources if you are reading this later.

Algorithm Tuning​

How can I inspect the built-in DSP tuning controls on ReSpeaker Mic Array v2.0?​

Applies to: ReSpeaker Mic Array v2.0 with XVF3000 and the matching official firmware

Last verified: 2026-09-01

Use the official usb_4_mic_array repository's tuning.py tool. The current v2.0 Wiki documents python tuning.py -p to list available parameters and shows parameter reads and writes, but it does not provide a universal preset or guaranteed pickup distance for every noisy room.

Prerequisites:

  • Confirm the hardware is ReSpeaker Mic Array v2.0 rather than another ReSpeaker revision
  • Install the USB control dependency and host driver required by the official guide
  • Keep a record of the starting parameter values and use a repeatable audio test
  1. Clone the official respeaker/usb_4_mic_array repository and enter its directory.
  2. Run python tuning.py -p to print the parameter names, types, ranges, access mode, and descriptions exposed by the active firmware.
  3. Use the documented python tuning.py <PARAMETER> form to read a value, and change only a writable parameter whose public range and meaning are shown.
  4. Repeat the same speech, distance, noise, and room test after each single change; keep the change only if the captured result improves without introducing a regression.

Success criteria:

  • The parameter list is returned without a USB-control error
  • The selected value reads back and the before/after recordings are compared under the same test conditions

Notes:

  • The public parameter table is an interface reference, not a validated noisy-room tuning recipe.
  • Poor pickup at a particular distance does not by itself prove a hardware defect; microphone placement, background noise, reverberation, firmware, and the host capture path must be controlled first.
