IR Format Guide

• IR Data Length

IR Length Options

Choose from two recording lengths:

200ms → Most devices don't need more than 200ms, so this is fine to start with.
500ms → Longer recording with more natural reverb. Good for BOSS, Iridium, and software apps.

Most devices only use about 21-46ms. If you choose longer IR data (like 500ms), your device will automatically cut it to the right length.

• Sample Rate

Sample Rate Options

Use 96kHz, 48kHz, or 44.1kHz folder to match your device.

• File Type

File Types

RAW: Natural sound response (recommended). *All files without "RAW" in the name are still RAW except MPT.
MPT: Minimum Phase Transform - Phase-aligned IRs for mixing different cabinets
