Easy to Integrate

AudioFile is a zero latency triggerable audio stimulus generator (ASG). It has a complete collection of analogue and digital audio outputs for easy integration. Choose from headphone and line, or optical S/PDIF for connection to a third-party amplifier. Standard TTL stimulus markers are compatible with 3rd party ERP/EEG systems.

• Audiofile's colour OLED display shows status information.
• Audiofile has a slot for a SD card for stimulus track storage. The files are stored as uncompressed 16 bit 44kHz wav files to avoid introducing audio artefacts. A 32GB card is supplied with AudioFile which gives over 8 hours of recorded stimulus.
• Audiofile is triggered with a TTL pulse, typically from a Visual Stimulus Generator (like the Cambridge Research Systems Display++ or Bits#) or data acquisition system. The PC parallel port works just fine too. A digital event code is also necessary, which controls which stimulus track is to be played.
• A trigger output indicates when a track is playing.
• Audio output is via an optical SPDIF output, or conventional analogue line out.
• A separate headphone output is provided.
• Audiofile is USB bus powered, so no separate power supply is required.
