a) Use of a PC with sound card and free / affordable / medium priced software
b) Simple devices like the Hifish Controller (for room acoustics measuring)
c)Affordable measuring systems with hardware (PC card, microphone) like e.g. Clio lite
d) Professional systems like Clio by Audiomatica, highly recommendable and the lowest priced in this category Interesting for commercial use: Clio.
Most measuring attempts fail because: 1) The measuring system is not set-up properly (contact problems), 2) By mistake the room acoustics are measured, instead of the loudspeaker.
Are you an electronics student or you have plenty of time, know how to check out a measuring system and understand the term Fourier transformation, then we recommend solution a) using programmes like Audiot or Audua (available on the Internet).
If you are unsure what or how much to measure or if you would rather like to measure the room acoustics we suggest b). Should you want to develop loudspeakers we recommend a), c) or d).
We have found a reasonably priced solution in section d) which we would like to introduce to you: Clio by Audiomatica.
CLIO X is a system: it is including the Audiomatica CLIO FW-03 interface as hardware and it is running the CLIO 14 STND Standard Software or CLIO 14 QC Quality Control (which has also extended features not only related to Quality Control). These two parts (hardware plus software) can not function separately.
CLIO 14 is the Next Step forward in the CLIO software family of products for the CLIO System, building up the well-known CLIO measurement suite.
CLIO X sports a completely new redesigned hardware.
The CLIO System with CLIO 14 software is a complete audio and electro-acoustic measurement instrument that gives state-of-theart solutions to laboratory, on-field and production-QC applications. CLIO 14 is designed to support and drive the new CLIO FW-03 hardware and is ready to accommodate its future developments.
The FW-03 USB Audio Interface sets new hardware precision standards for the CLIO System.
CLIO 14 Software is the new measurement software for the CLIO System. CLIO 14 software is fully compliant with Windows 7, 8, 10 and 11.
Compared to other measurement systems, CLIO concentrates the power of many different instruments into a single one. Three different measurement techniques are available for system identification and characterization:
While other instruments offer one single possible measurement choice, CLIO permits you to view the physical phenomenon like frequency response, impedance or other parameters, from different points of view. The final result will be then validated by the consistency of these measurements: as any expert technician knows, this is the correct approach that should always be adopted.
The following specialized control panels are dedicated to other specific measurements:
Beyond measured results you get sophisticated post-processing tools for:
Using all the aforementioned measuring and post-processing techniques it is possible to tailor powerful Quality Control scripts that will manage and identify any production line of electronic or electro-acoustic devices.
This measuring system is absolutely fascinating. Even professional loudspeaker manufacturers think that way. To familiarise yourself with Clio we give you some details.
Both Clio hardware measuring systems consist of a switch controller/measuring box:

HiFish Audio Test-CD ACD Price EUR 15,00 excl. VAT: € 12.61 / $ 14.24
Every home-made speaker may be optimised (not designed and developed). Even the sound of purchased speakers, may be improved on, since this system is capable of measuring the influence of bookshelves, wing chairs, damping carpets etc.
Well, if this is not enough, there will be additions to the system that may be integrated into your current hi-fi, enabling an analysis without dismantling your speakers. A programmable crossover and a high-end pre-amp have been announced already.
The technology is not yet available for 64-bit systems and is not available for Windows 10.
Summary of review in Hobby HiFi 2/2001: "A terrific gadget, this Audio Controller by HiFish: sound level measuring is done in a jiffy and with the use of the test CD even extensive frequency response tests and room acoustics analysis are performed without a hitch. The accurate calibration of a home cinema system is as easy as the determination of the ideal positioning of the speakers and establishing the hot spot. It's a useful tool in setting-up Helmholtz absorbers (so-called bass traps) and crossover networks. Short and sweet: a tool too good to miss in a hi-fi home. "
Docking Station A docking station is also available now. The station generates the test signals itself, thus replacing the CD player. The station's frequency response is 16 Hz to 20 kHz and is able to generate single tones, sine sweeps and stepped tone bursts. Price EUR 195,00 excl. VAT: € 163.87 / $ 185.17
