Active DJ Studio 4.2

Active DJ Studio 4.2 is an affordable and powerful video conversion solution on personal computer. Active DJ Studio is an ActiveX control adds sound playback and mixing capabilities to multimedia applications.

Active DJ Studio comes with built-in decoding capabilities in order to decode most common sound formats like MP3, WAV, Ogg Vorbis and many others: it can load different sounds at the same time on different players and, thanks to the use of DirectSound, allocated players can have separate Volume, Tempo, Equalizer and other effects.

 An embedded automatic fader can easily mix audio tracks loaded inside a playlist with an accurate and configurable fade-in/fade-out.

Thanks to the integration with DirectShow, Active DJ Studio can load and play video files using formats whose specific codec is available on the target machine and, through the mentioned players, it can apply different sound effects (equalization, volume, DMO effects, etc.) to the sound portion of a video file.

Active DJ Studio is open to the external world of DSP effects: it can work with custom DSP effects developed by the developer himself and also with the multitude of VST effects available on the Internet.

Enhancements:

1. New methods

• GetPitchFloat
• SetPitchFloat

 2. Fixed bugs  

• When using more than on instance of the control, the SilencePositionAvailable event will report wrong values.
• Allocating several instances of the control on several forms that will be opened and closed could cause issues with the visual feedbacks.
• Changing visual feedback's settings during playback can cause a GPF
• Calling the CloseSound method immediately after a call to the RequestSoundExportToWav method can cause a GPF: in any case, note that calling the CloseSound method immediately after a call to the RequestSoundExportToWav method is not a correct behaviour and must be avoided.
• WAV ADPCM format files can cause a GPF during a ReadSoundInfo method's call
• Changing the width of Spectrum bands through the Spectrum.BandWidth property doesn't produce any visible effect.
• Starting a recording session, through the Active Sound Recorder control, can cause a discard of the loaded song from memory.
• If no sound is loaded inside a player, the RemoveTrigger method doesn't remove the given trigger.
• The manual BPM calculation, performed through a call to the RequestSoundBPM method, will cause a GPF on sounds loaded inside a memory buffer.
• If more than one instance of the control has been instanced, the Waveform analisys will fail for all of the instances different from the first one.
• The visual feedbacks suffer a momentary stop of their graphic rendering when one of the players completes playing the loaded sound.
• Setting the ScaleUnits, SoundsDirectory, ForwRewGranularityType and ForwRewGranularity properties from instances of the control different from the first one will have no effect
• If both Active DJ Studio and Active Sound Recorder are instanced on the same form the sound card's speakers enumeration could fail.
• If both Active DJ Studio and Active Sound Recorder are instanced on the same form, the enumeration of players available inside Active DJ Studio could return a wrong value
• Making a call to the PlaySoundRange method after disabling the automatic fader, through a call to the Fader.Exit method, could result in a GPF.
• Sounds playback is not always good on AC97 based sound cards.
• After a call to the Fader.Exit method, on a fader initialized in FADE_SINGLE mode, the SoundDone event is fired over and over again
• Loading a MP3 file from an Internet URL through the LoadInternetStream method can cause a GPF
• Trying to obtain the CDDB title of a CD's track containing data instead of audio can generate an exception
• Mixers related functions don't work under Windows Vista
• Sounds loaded through the LoadEncryptedSound method cannot be mixed.
• Memory leaks are generated when instancing the control inside a web page.
• The control doesn't register correctly on Windows 98 and Windows ME.
• Positioning through the SeekSound method is not performed correctly on AAC and MP4 sound files.
• Speakers assignment is not reliable on Windows Vista.
• CDDB information is not always correct.
• With some specific CD, whose author/title conbination exceeds 24 characters, it's not possible obtaining the CD cover from Amazon web service.
• Damaged AAC, MP4 and M4A files can crash the control.
• Equalizers don't work correctly.
• The mixer volume change on USB devices having one single channel (for example USB phones) is not managed correctly.
• Passing an invalid memory pointer to the LoadSoundFromMemory method can cause a GPF.
• The PlaySoundRange method fails if the ScaleUnits property is set to a value different from milliseconds.
• Speakers assignment is ignored by LoadInternetStream and CreateSoundFromPCMBuffer methods.
• 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.
• When a playlist has been performed completely, and no loop has been set, the SoundDone event is raised over and over again.
• If more than one instance of the control has been created within the same application, the SetPlayerSpeaker, SwapSpeakersRearAndCenter and SwapPlayersSpeakers methods will work only with the first instance.
• The GetMp3Tag1Field method returns a string with spurious characters.
• If a LoadSound call fails, a memory leak is generated.
• The SetRewindOnEOF method doesn't work if no sound is loaded into the player.
• The LoadSoundSync method won't generate the SoundSyncLoaded event (with error code) if the file to load doesn't exist.
• During the execution of two playlists with automatic fading, the player reported by the SoundLoaded event will be always the first one.
• The RequestSoundExportToWav method doesn't work as expected
• Under Windows Vista mono files are not played if speakers management is disabled.
• Sound files of unknown format could crash the control during a loading session.
• The RequestSoundSilenceDetection method could generate fake values if no sound is loaded.
• The automatic fader could generate an OLE automation error.
• When loading a CD track, the waveform analysis and the silence detection could generate fake values.
• CD tracks cannot be loaded into a playlist.
• The call to LoadSoundFromRecordingSession could generate an exception.
