Audio Capture Key features

Input Selection

River Past Audio Capture enables you to select the input port with an easy and obvious interface, whether you are recording from microphone, line-In, or speakers.
It is the only audio recording software which enables you to record from a DV camcorder or VCR connected to 1394 port. This makes it extremely easy for you to move your newer collection of DV tapes to your computer.
Output Formats

River Past Audio Capture supports a wide range of input formats.
Codec Control

With WAV, MP3, audio-only AVI output, and WMA, you have the full control over sample rate, channel, resolution (8-bit or 16-bit), and bitrate.
When recording WMA using profiles, you have the choice of many pre-defined profiles, targeted at different usages.
Pause Control

You can pause the recording in River Past Audio Capture, and restart later. This enables you to have multiple segments of recording in a single audio file.
Universal Converter

By recording from the speakers, River Past Audio Capture can be used as a universal audio converter, regardless where the audio is from.
For example, you can start playback of a RealMedia or RealAudio file in the background with Real Player, and record from speakers. This turns River Past Audio Capture into a RA to MP3 (or RA to WMA) converter.
You can use the same method to convert MIDI to MP3/WMA.
Sometimes it is the only way to convert some audio formats. For example, Napster and MusicMatch use encrypted WMA audio, which only their software can decode. To convert the music you already purchased to MP3, you can either burn a CD from their software, and then rip and convert it, or you can use River Past Audio Capture to record through the speakers.
