   Patches and Upgrades

ActiveX version (asrecmms.ocx) 2.3.0.5 (June 11, 2008)
Multimedia engine version (AdjMmsEng.dll) 7.5.0.0 (June 18 , 2008)

Fixed builds can be downloaded using the same link, username and password received after purchasing the product: if you should have lost them or if they shouldn't work anymore, please, contact our Technical support.

VERY IMPORTANT: Before proceeding with the installation of updated versions, don't forget to close all of the running applications and to UNINSTALL the existing version: missing this step could prevent the new version to run correctly on your development PC.

Fixed Bugs (since version 2.0)

  • Editing a recording session loaded from a damaged M4A file will cause a GPF.
  • Trying to delete a portion of sound, through the RecordedSound.RequestDeleteRange method, could cause loosing the full sound.
  • After playing back a range of recorded sound, through the RecordedSound.PlayRange method, it's not possible starting a new recording session.
  • RecorderStartFromMemory method doesn't work correctly
  • Graphic bars settings are not updated immediately after a call to the GraphicBarsManager.SetGraphicalSettings method.
  • Duplicated CDs can sometime report a wrong CDDB identification number so, during a ripping session, tags could be missing.
  • Methods returning a string could end with spurious characters.
  • An error could be raised when launching two different applications both of them using our control.

  • A recording session on a file in WAV format could be interrupted without reason after a few minutes.
  • Recording sessions in WAV format, performed from a control instanced on a secondary form, could cause an exception the second time the container form is opened.
  • There is a discrepancy between the volume set using the SetInputDeviceChannelVolume method and the one reported by the GetInputDeviceChannelVolume method.
  • Closing the container form while a recording session is running could cause an exception.


PRODUCT HISTORY

Version 2.3.0.0

New features

  • Improved control's loading speed

SPECIAL NOTE TO DEVELOPERS: in order to speed up the creation of the form containing the recorder control, we had the need to make a slight modification to the internal architecture of the multimedia engine and of the recorder control. After this modification, the following methods will not be immediately available and your application will have to wait for the new InputFormatsAvailable event before calling them:
  - GetWmaEncodingBitratesCount
  - GetWmaEncodingBitrate
  - GetSupportedRecordFormatsCount
  - GetSupportedRecordFormatDesc
  - GetWmaEncodingVBRQualitiesCount
  - GetWmaEncodingVBRQuality

The usage of the new InputFormatsAvailable event is shown inside the following updated samples:
- SimpleMp3Rec
- SimpleOggRec
- SimpleWavRec
- SimpleWmaRec

If your application shouldn't be using the mentioned methods, there should be nothing to be worried about and you won't have to modify your code.
