3 August 2025 at 10:08 pm #1133In the current version of “FIR Designer M” there is not a way to copy all DSP settings from one channel to another in one go. But we have added this to the TODO list.
Many of the tabs in the workflow have copy and paste functions, so you could copy most of the settings between channels. However Auto Mag and Auto Phase functions depend on the Import tab measurement, so you need to load the same measurement on both channels (and make sure settings of every workflow tab are the same) to ensure the DSP is the same across multiple channels when using AuditionDSP.
AuditionDSP in “FIR Designer M” runs DSP for as many channels as FIR Designer M is configured for.
In “FIR Designer” (which is only one channel of DSP), AuditionDSP has an option to run the DSP in stereo.

3 August 2025 at 9:16 pm #1129Files received. These are unique enough – with headers and sparse data – that we may be able to make a custom importer.
One question… The file names and the 2nd column header both explicitly say “THD’, which I presume means total harmonic distortion. If so, then these are not response measurements. Am I missing something?

3 August 2025 at 8:03 pm #1126>> “Pause FIR Auto M & P Updating” pauses ALL calculations including IIR and GPD in system Export tab.
Yes. Everything in the workflow from Auto Mag through to channel Export and System Export is paused. We will consider either:
– disabling the System Export tab when “Pause FIR Auto M & P Updating” is checked, or
– unchecking the “Pause FIR Auto M & P Updating” when the System Export tab is clicked, so that the system export get correctly updated.>> So it’s just for slow computers affected by auto calculations?
Yes.
Generally, I ask that you be patient. We have lots of work to do and many other customers to also help. We will look at your requests at the appropriate time.

3 August 2025 at 6:38 am #1122>> HD measurements from Audiomatica CLIO
Can you email us a few example files? I’d like to see if there’s any additional header information in the TXT file, before the columns of data. If there is, then it makes it much easier to implement a custom file loader.

3 August 2025 at 6:35 am #1121“Pause FIR Auto M & P Updating” intentionally pauses ALL calculations from Auto Mag through to export. It allows fast editing of IIR filtering, without being slowed down by the Auto Mag and Auto Phase calculations. Once you are happy with the IIR filters, uncheck “Pause FIR Auto M & P Updating” to continue your work.

3 August 2025 at 6:30 am #1120>> Unfortunately I can’t, voicing tab use channel target, not system target.
True. But since the Voicing tab shows the combined response of all channels, and since the displayed Target is a combination of the system and channel Target, you can look change “edit” channels and get a good sense that the combined response meets your System target.
>> Also System Export tab don’t have view for combined filtered IR and Step, which I think is useful
We have considered this, but since each channel’s processing can have a different sample rate, it’s very complicated to calculate a combined IR and Step for the system. 2nd view does have a combined wavelet view.

2 August 2025 at 9:09 pm #1112In “Preferences”, check “User per-channel plot checkboxes”. This allows each channel to have different plot display preferences on most tabs.

2 August 2025 at 9:07 pm #1111Noted. We’ve added this to the TODO list.
BTW you can compare the response to target on the voicing tab.

29 July 2025 at 1:16 pm #1107Hi Eddi,
Firstly, I should say we don’t advocate any particular EQ approach. We provide the tools to enable you to experiment with whatever approach you like and works for you. That said….
We do suggest using the average of multiple measurements from a coverage area, and not a measurement from a single location. (In the car this might mean, for example, multiple measurements within ~30cm of the nominal head position for the front seats.) We also suggest fairly broad smoothing – e.g. 1/3rd or 1/6th octave – on the Auto Mag to avoid narrow, high-q boosts.
Separate boost and cut parameters for the Auto Mag are under consideration and on the TODO list, but I can’t say when we might get to this.
Best regards,
EA Support
29 July 2025 at 11:00 am #1106Hi Alex,
File import information is at
I presume you’re referring to text import so see the section “Text (*.txt) and CSV (*.csv)”.
Yes, if a file has only 2 columns – frequency (Hz) and magnitude (dB) – then a 3rd column of zeros needs to be added. This can be done in a text editor, Excel and maybe Apple Numbers or Google sheets. It’s on the todo list to provide for 2 column frequency and magnitude loading, but for now 2 column is interpreted as the time samples of an impulse response – column 1 are timestamps and column 2 is the sample value.

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.
