May 2019 Update: This web page and the contents are under revision in anticipation of the new version release of Filter Hose (full version and LT version). We apologize for any inconveniences.
Newest release of Filter Hose: v2.1 (April 2018)

Filter Hose is a unique FIR (finite impulse response) filter creator software. It enables user to edit time domain data to construct a FIR filter very quickly and experiments with different filter properties (tap length, windowing, processing delay, etc) very easily. To speed up the FIR creation, Filter Hose provides several frequency domain target responses.


Three Easy and Quick Steps
Load a Measurement
Direct ASCII file load: EASERA, Systune, ARTA, Room EQ Wizard, HOLM Impulse, FuzzMeasure and Smaart
Direct binary file load (with author's permissions): EASERA, Systune, ARTA and Monkey Forrest
Manual frequency domain data input
Select a Target Response
Edit the FIR Filter
Features:
  • Easy to quickly create FIR filter based on a measurement or a user defined input
  • Create mixed, linear-phase and minimum-phase FIR filters

Frequently Asked Questions

Where can I download the demo/trial version?
- There is no demo/trial version. However the LT version is available (please scroll down) for new user to try. LT version is a freeware.

Does Filter Hose import/export wave file?
- Yes, v2.2 and beyond.

Is Filter Hose compatible with Mac?
- It is only compatible with PC, but it can run from a PC Virtual Machine.

Can Filter Hose make filters with different sample rate?
- The filter calculation depends on the input/measured data, therefore the result follows the input sample rate. If different sample rate is desired but one input file is available, please use the Manual Input.

Can Filter Hose convert wave file to text?
- No, however Filter Hose can convert text file to wave file. User is able to export wave file on the input/filter/output data.

Does Filter Hose export fixed/floating point wave file?
- Fixed: 8, 16, 24 bit and Float: 32, 64 bit.

I can't open the installation zip file.
- The software is delivered in a password protected zip file. Please make sure you use WinZip, 7zip or other zip extractor programs.


What version of measurement software does Filter Hose recognize?
- Please refer to the user guide to see which version of the measurement software (EASERA, ARTA, Smaart, etc) we tested Filter Hose with.

Is Filter Hose a multi-language software?
- No, Filter Hose uses English language. If your window operating system is not running using English, there may be problems in running Filter Hose. Please make sure you choose English under region and language of the Operating System. We apologize for the inconvenience.
- In most cases, Filter Hose recognizes dot (.) as the decimal separators.

What is the cost for upgrade and/or update?
- There is no cost associated with upgrade and/or update for Filter Hose.

Is there a wave file import limitation?
- There are so many version of wave files. Filter Hose wave file import focuses on a mono wave file that contains an impulse response. Should you find a difficulty to load a wave file, please try to edit it first in Audacity or other programs and resave in 16bit or 24bit PCM.
User Testimonials

Filter Hose has completely revolutionized my work flow in sound reinforcement. The ability to quickly create custom minimum and mixed phase ​FIR filters that optimize the cumulative effects of equipment, installation, and acoustic environment, is amazing. Hitting your acoustic target, whether flat or something more esoteric, has never been easier. If you can collect good measurements in the field, Filter Hose will help you make the most of whatever FIR hardware you use.

Filter Hose is a powerful FIR creator software. It makes my tuning job easier. From the measured data, Filter Hose can perform post processing and then just simply select the target I want. This was my dream software which is now available on my fingertips.

Filter Hose is a complete FIR filter generation tool. I can collect data with any of my measurement platforms, and go straight to Filter Hose for post-processing and FIR generation. The Export functions are quite versatile, and my Rane HAL opens the files flawlessly. I can't really think of anything that I want to do with FIR filters that it can't do. It is the audio practitioner's complete FIR generation environment.
