Imm-6 calibration file download

Find the iMM-6 calibration file you downloaded from above in step 3 and double-click on it. You should see the calibration file appear.

These instructions are based on the instructions given on the Studio Six Digital website. For use in AudioTool, you will simply need to rename the file so that it has the. Your iPhone and desktop PC will need to be able to 'see' each other to transfer files.

Your wireless router should not be blocking port If you haven't set your wireless router specifically to do this, it shouldn't be blocking this port. You will need the serial number that is printed on the back of your iMM-6 carrying case to access the unique calibration file for your iMM The Calibration Screen will be displayed.

Tap the Files button to bring up the Files screen. This is the address for direct file transmission to your iPhone. Visit the Dayton Audio calibration download tool , where you will be prompted to enter the serial number from the case of your iMM After entering the serial number, your download will start.

Note: In order to use your iMM-6 as a calibrated measurement microphone you may be required to purchase an app for your tablet or smart phone. Help for Android and iPhone users: There are many applications in the market that provide the smart phone user with audio measurement software.

We do not recommend any specific apps, however, in an attempt to assist the new user of an iMM-6 we have listed links and some helpful pointers below. Download the calibration file by clicking on it. Save the file. It will say "Headset Mic 1" when connected. Here the Sens value is found by noting that since it takes a sound that is To convert to 1 VRMS you could use the relationship that.

Now you need to know the speaker impedance, which is typically 4 or 8 ohms "nominal". For an 8 ohm speaker, the square root would give 2.

See the dB section for computation details. You would thus have to reduce all the manufacturer's dB values by this amount to convert to a 1 VRMS reference.

However , it is strongly recommended that you not rely on speaker manufacturer's curves as anything other than comparative reference data for purchase decisions. If you need to know the actual response from a particular speaker in your particular setup, you really need to calibrate it yourself. Note that. CAL files are not restricted to microphones and speakers, nor even to conventional transducers.

It is perfectly possible to have a. Of course, you could have. CAL files for current-to-voltage transducers or anything else you have in mind. All that is needed is a conversion between your units and volts, which is the native signal for the sound card. Also, note that Curve files with a.

CRV extension use the same format as. CAL files, except the 'Unit:' and 'Sens:' lines are ignored. Curve files may be more appropriate for some applications. FRD file format is an emerging industry standard for calibrated microphones.

It is similar to. CAL except that instead of just frequency and dB columns, there is a third column for phase. The typical. However, such an. FRD file can be used with Spectrum Curves just as it is if you only need a relative calibration, where you just want to see the shape of the frequency response without measuring absolute levels.

You can manually add the Unit and Sens lines with Windows Notepad or any text editor , and re-save the result. To keep the file compatible with other applications that use the.

FRD format, use asterisks to make the Unit and Sens lines look like comments:.
