Product history

Version 11.0.0.0

New features

•	No more need to rely upon external encoders for MP3, Ogg Vorbis and Opus formats, allowing an increase of around 60% of the encoding speed. See the EnableInternalEncoders method for possible backward compatibility issues.

•	Added support for downloading remote files from HTTP and FTP sites

•	Added support for recording the audio track of video clips available on Youtube

•	Added support for retrieving rectangles of each channel displayed on the waveform analyzer

•	Added the possibility to set the folder where temporary files created by the component are stored

•	Added the possibility to obtain the unique identifier (GUID) of a CoreAudio device

•	Added new builds of the component specifically compiled against .NET 5, 6 and Core 3.1

Version 9.0.0.0

New features

•	Added support for playing sound while manually scrolling the waveform scroller through the mouse

•	Added support for recording and exporting in AAC+ format through the external encoder FdkAac.exe

•	Added support for playing recorded sound in reverse

•	Added support for playing recorded sound at a higher speed with the possibility to keep voices at their original pitch (tempo)

•	Added support for recording Internet streams in HLS format (HTTP Live Streaming)

•	Added the possibility to split a stereo recording session from a Wasapi capture or loopback device into two mono output files

•	Added the possibility to switch the mono output files of a stereo splitting recording session

•	New options for the waveform analyzer

- the waveform can now display detected peaks based upon absolute values

- more control over the format of the time string displayed on time rulers

- optional automatic vertical zoom for waveforms with low volume level

•	Peaks displayed on the waveform visual feedback during recording and playback are now reported to the container application through a dedicated event

•	Added support for retrieving, during recording and playback, peak levels and RMS (Root Mean Square) levels

•	For capture and loopback devices, attached to a WASAPI stream mixer, added support for retrieving peak levels and RMS (Root Mean Square) levels for each of the attached devices

•	Added the possibility to retrieve from the waveform analyzer the buffer containing waveform's peaks
