Active Sound Editor 관련 정보

오디오 편집 및 사운드 분석을 통해 응용 프로그램을 개발합니다.

Active Sound Editor is an ActiveX control that adds sounds editing and sound analysis capabilities to multimedia applications. It can perform various operations with audio data such as analyzing the sound's waveform. It includes rich visualization capabilities like zooming, panning, filtering, effects, equalizing, tempo change, custom DSP, sliding volume and volume automation. It supports encoding in several audio formats.

Active Sound Editor is an ActiveX custom control that makes it easy to add sound editing capabilities to applications. It is integrated with DirectShow codecs and the BASS library, which allows you to decode most common sound formats including MP3, WAV, Ogg Vorbis and many others. It provides advanced features to allow an application to access and modify audio data, including support for editing metadata and tags. You can also create your own sounds by composing audio files from scratch using the internal sound composer which comes with support for multi-channel audio (up to 8 channels or 7.1): All sound items added to the composing session are layered, meaning that they can be added, removed and modified before composing the final mix and exporting to a destination file.
