Version 2.3.0.0

New features

•	Improved loading speed

New events

InputFormatsAvailable

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.

Version 2.0.0.0

New features

•	Encoding and ripping in AAC and MP4 formats (through external Faac.exe encoder)

•	Encoding and ripping using Codecs installed inside the system, through Windows ACM (Audio Compression Manager)

•	Ripping of predefined portions of CD tracks with resample capabilities.

•	Full support for half-duplex devices like Philips SpeechMike™

•	Possibility to resample sound data coming from a ripping session, changing frequency, channels and bits per sample: this will allow creating smaller output files with lower quality.

•	Restarting a stopped recording session in append, insert or mix mode with the possibility to define the position where the new recording session will be inserted or mixed with the existing one.

•	Cutting and removing sound portions, useful for rewind operations

•	Inserting a portion of silence at a given position

•	Pre-loading contents of a recording session using sound data coming from file, memory, clipboard and Internet sound files: sound data coming from the mentioned sources can be resampled before being stored

•	Resampling and exporting the current contents of a recording session (or portions of the same) in all of the supported formats

•	Recording from an Internet stream (HTTP, FTP or MMS) in various formats (MP3, WMA, OGG Vorbis and AAC)

•	Sound waveform analysis with the possibility to obtain the sound waveform in bitmap form

•	Mixing the recording session over a background sound (it could be also a sample in loop mode)

•	Support for clipboard import/export

•	Availability of a visual sound waveform analyzer that will allow zooming inside the song waveform and selecting a portion for editing features

•	Availability of graphic bars for external visual feedback implementation

•	Possibility to apply the Automatic Gain Controller to the recording channel

•	Uploading the contents of a recording session to a FTP site
