 Added: Selected input source is now gold

 

Audio Scope

 Fixed inconsistent mic settings text, in Mono, Mic only mode


AudioTools 3.9:


Fixed: Crash in SmaartTools when changing graph type.


AudioTools 3.8:


General:

 -Streamlined orientation changes in SPL Meter and SPL Pro

 -Updated mic gain in iOS5 for iPad, iPhone 3GS, iPod touch 3

 -Fixed iAudioInterface low gain issue


AudioTools 3.7:


Stipa:

 * Added STIPA speech intelligibility module


General:

 * Improved orientation handling

 * Built for iOS 5 (Note: iOS 5 improves audio input quality and provides gain control for most devices)

 * Added High and Low mic ranges on iOS 5 for devices that support this


Save / Recall:

 * Added: After entering a file name, a  “Store” / “Cancel” dialog box appears


iAI2:

 Changed: Disabled DC stripping, now in iAI2 firmware

 Added: Now discovers accessories while app is running

 Fixed: Level Meter and Phase Meter would always crash on audio route change

 Fixed: Blank space would appear below status bar after returning to menu from several functions


Smaart:

 Fixed: graph could get zoomed in or out too far

 Fixed: dB labels could disappear on spectrum graph, iphone


RTA:

 Added: Max and Min now saved in XLS file, if enabled

 Added: Start of measure is delayed to prevent picking up tapping noise

 Added: If Average decay mode is selcted, Max and Min bars reset at delayed start

 Added: In Average mode, last 1/2 sec of response is ignored for max / min bars and average to remove button tap noise

 Added: Demo video added to Video Center

 Changed: Cursor only to RTA band center frequencies

 Changed: Max & Min bars now store actual max and min while in average mode

 Changed: Double-tap now also clears averaging and max / min bars

 Logic:

  - clear max / min one sec after start, if averaging was also cleared -- not after just a pause / run

  - double tap to clear averaging (all), and max / min bars
