Component programs of DSSF3 and RAL / RAD / RAE
YMEC's sound measurement software, DSSF3 and RA series (RAL, RAD, RAE) consists of three programs; Realtime Analyzer (RA), Sound Analyzer (SA), and Environmental noise Analyzer (EA). 

Covered fields are audio measurement, electronic measurement, room acoustics, and acoustic analysis of noise, human voice, musical instrument, and biomedical signals like heartbeat and lung sound. Application notes in those fields can be read. Click the link below.

Trial and order of DSSF3
DSSF3 has four versions as in the table below, but the installer is common. Get the program here. All of functions of the highest version (Environmental Noise) can be evaluated during a trial period of 30 days. After purchasing the license, the password for each version will be issued for releasing the protection. Order the license at YmecStore. Note that DSSF3 is always updated to incorporate users suggestions and requirements. Users of DSSF3 are recommended to perform Online update to keep the software up to date. See DSSF3 news for upgrade information. 

About RA series (RAL, RAD, RAE)
Previous version of the DSSF3 (ver.3) has been released as RA series. Basically, RA series (RAL, RAD, RAE) and DSSF3 have the same programs, but some of the advanced functions are not available. The latest OS, PC, soundboard, or USB interface may not work with RA series, because no future upgrade is scheduled. In that case, try DSSF3.

How to select the software?
If you are not sure which version is suitable for you specific purpose of use, see the related Q&A topic: How to select the software
