Introduction
Audio Sound Recorder for .NET (AudioSoundRecorder.dll) is a .NET custom control developed by MultiMedia Soft that makes it easy adding sound recording capabilities to applications written with Visual Studio.NET.
Audio Sound Recorder for .NET is designed to work directly with your sound card or with your CD/DVD player, so you can record almost any audio, including that from a microphone, a line-in jack or a CD player (CD ripping), at near-perfect quality.
Recorded sounds can be kept in memory for later use or stored on the hard disk using several formats: WAV, MP3, WMA, OGG Vorbis, AAC, MP4, AIFF, AU, W64, PAF, SVX, NIST, VOC, IRCAM, PVF, CAF, FLAC and RAW; ACM codecs installed inside the system are supported as well; once a recording session has been completed, it's possible to hear recorded sound through the embedded playback system: if you need more sophisticated playback features (like changing tempo or pitch), consider using this component in conjunction with our
Audio DJ Studio for .NET component.
Active Sound Recorder allows a deep analysis of the recorded sound waveform with rich visualisation capabilities like range selection, zooming and panning. Recorded sounds can be edited, resampled, mixed with other sounds and exported to different formats: the ideal solution for implementing powerful Dictation Software Applications.
The integrated Sound Activation System allows pausing a recording session automatically when no sound is being heard: this will help saving valuable space both in memory and on disk.
Active Sound Recorder comes with
many Internet related features: it can record sound data coming from Internet URLs (HTTP, FTP or MMS): this allows recording directly from Internet radios streaming in WMA, MP3, OGG Vorbis and AAC formats. Contents of a recording session can be uploaded to a FTP server. Thanks to the integration with
FreeDb servers, the control can obtain CDDB information about the CD currently in ripping phase and, if available on the
Amazon web site, the control can obtain the CD cover pictures as well.
Custom DSP effects are also supported: you can create your own DSP effects and apply them to the sound being recorded.
Let's see a brief summary of the available features:
Recording from any DirectSound compatible sound card available inside the system
Support for half-duplex devices (like the Phillips SpeechMike™)
Recording in the following formats: WAV, AIFF, AU, W64, PAF, SVX, NIST, VOC, IRCAM, PVF, CAF, FLAC, RAW
Recording in MP3 through the external Lame.exe encoder
Recording in OGG Vorbis through the external OggEnc.exe encoder
Recording in AAC and MP4 through the external Faac.exe encoder
Recording in WMA through the external Windows Media Audio modules
Recording through installed Windows ACM codecs (Audio Compression Manager)
CD ripping of full tracks with resampling capabilities
Ripping of predefined portion of CD tracks
Real-time visual feedback (VU-Meter, Oscilloscope, Spectrum, Waveform display)
Events for reporting memory or file size occupation in real time
Sound Activation System (automatically skips silence periods)
CDDB database queries through FreeDb servers
Restart of a stopped recording session in "Append mode", "Insert mode", "Mix mode" and "Overwrite mode"
Sound editing basic capabilities with possibility to export portions of sound to the clipboard
Creation of graphic bars for custom displaying of Vu-Meters, Spectrum and Progress bars.
Waveform analysis with support for generating the waveform bitmap
Advanced waveform visualisation for editing purposes through the embedded Waveform Analyzer
Support for recording directly from sound files stored on disk, memory buffer or clipboard with resampling capabilities
Support for recording directly from HTTP, FTP or MMS sites with resampling capabilities
A background sound can be applied to the current recording session, also in loop mode
Support for exporting to file contents of the latest recording session with resampling capabilities
Automatic Gain Controller applied to data coming from an input channel
Uploading of the last recording session to a FTP server
Support for custom DSP effects
Support for switching the output file without stopping the recording session and without loosing any sound data.
