Hi Tim
The normal signal for RASTI measurement is a specially modulated noise signal, according to the IEC 60268-16 standard. The standard also mentions the possibility of using an MLS signal, in which case the modulations are not appropriate.
Using WinMLS you can measure impulse responses with MLS, and one of several post processing options is calculation of RASTI. You will find this under Room Acoustics->Parameter Settings. With this technique the full STI can be calculated after spending the same amount of measurement time. We therefore recommend that the STI is used instead of, or at least in addition to, the RASTI parameter.
For further information, see the WinMLS user's guide.
Best wishes Johan L. (responsible for WinMLS room acoustics development)
