SAMPLE RATES
Inside the IR folders listed above, there are four folders corresponding to different sample rates (44.1, 48, 88.2, 96).
For digital IR loaders, use the IRs with the sample rate that matches your session – if you’re recording at 48 kHz, use IRs found in the ‘48’ folder, etc.
For hardware IR loaders, use the IRs that match your unit’s sample rate. We have some of the most popular units’ sample rates listed in the table below. If your unit does not appear in the table, check either the unit’s manual, or the manufacturer’s website for the sample rate.
Unit |
Line 6 (Helix, HX Stomp, POD Go) |
Mooer (Radar, GE300) |
Fractal (Axe-Fx) |
Two notes (Torpedo, C.A.B. M) |
HeadRush (Pedalboard, Gigboard)
IR LENGTH
Sample Rate
48 kHz 44.1 kHz
48 kHz 96 kHz 96 kHz
All of our IRs are 150ms in length. For the most realistic acoustic tone, you’ll want to load the full length of the IR.
Many units truncate the length of IRs to save on DSP (Helix, Mooer, etc.). The truncated length is still enough to vastly improve your tone and is perfect for live settings, though we recommend using the full length for studio recording.
