25 July 2025 at 9:15 am #1101Before you send us any files, on the “Measurement Averaging” “Save” tab, for “Format: WAV file – Impulse Response…”, experiment with setting the “IR start (ms)” further negative before saving the file.
On the “Measurement Averaging” “Average” tab lower plot, look at the impulse response (by clicking on “IR Samples”) and you will likely see some of the impulse response extending negative. If so, then this needs to be saved in the WAV file to ensure the whole response – particularly at lower frequencies – is retained.
Setting “IR start (ms)” further negative effectively add bulk delay to the saved WAV file, but with anything other than minimum-phase responses, it’s the only way to retain the response accurately, since the response extends earlier in time than the IR peak.

25 July 2025 at 8:35 am #1100Understood. It’s already on the TODO list but it’s not simple to implement in our codebase.

25 July 2025 at 8:32 am #1099Please email* us a download link to the files you’re averaging, screenshots of the “Measurement Averaging” “Load & Setup” & “Averaging” tabs, and an “Averaging Session File” and we’ll take a look. I’m fairly sure I know what’s happening with the WAV export – there’s probably not enough samples being saved prior to the IR peak – but I need to confirm.

24 July 2025 at 9:13 pm #1092>> In addition to fixing AutoIIR, please consider adding a checkbox labeled
>> “Ignore system target” in the Channel Target tab. I believe this could be useful…I’ve added this to the TODO list.

16 July 2025 at 9:12 am #1079Our single-channel products are aimed more at EQ’ing full speakers and system tuning, but can be used for multi-way loudspeaker design – by using one channel project per driver. However it’s not possible to see the combined, summed response of all drivers. (FIR Designer allows multiple program windows to be be displayed so it’s possible to look at, and work on, all channel projects simultaneously.)
FIR Designer M is aimed at multi-way loudspeaker design and shows the combined response at every stage of the workflow. It also has tools for viewing off-axis responses with the multi-way processing.
So, yes, if your focus is designing processing (including crossovers) for multi-way loudspeakers, FIR Designer M is the best product.

19 June 2025 at 4:27 pm #1075What is the effect of running a 96kHz filter on the 93675 hZ DSP of Hypex? Will it work with a slight frequency offset in the magnitude response?
93.75 kHz is 97.66% of 96 kHz. So the net effect of running a 96 kHz designed filter at 93.75 kHz is that the effective frequency response will be 2.34% lower in frequency. (For example a response peak designed for 18 kHz will actually be at 17.59 kHz.)

17 June 2025 at 11:26 am #1073Take a look at sections 5 and 7 of
I always set Filter-Delay to 0 in FIR Designer ….. This is to slightly increase the resolution of the low frequency control within the limited number of filter taps.
The overall filter length is what mostly affects the low frequency resolution and control. The delay setting mostly relates to the type of filter you are making. With a delay of 0, you’re making a minimum-phase filter, which you could also do with IIR filters, or a mix of both IIR and FIR.

16 June 2025 at 6:51 pm #1071That sounds like a question for Rational Acoustics. It’s beyond the scope of our software support.

13 June 2025 at 7:41 am #1068Hi, yes they support FIR with 1500 taps per channel, 3 channels in case of DSP3-213.
Great, that’s 16ms per channel. So to clarify, what you need is FIR Designer to be able to create FIR filters at 93.75 kHz?
We would consider enabling 93.75 kHz if we could also emulate the Hypex IIR filters, as part of complete preset creation. For that we need IIR filter information from Hypex – see the “FIR Designer Brand Integration” link above. If you have contacts at Hypex, please reach out to them. We have not had any success contacting them in the past.
