Abstract: 

To support the development of new low cost instrumentation particularly suited for bioacoustic studies, CIBEA is involved in testing instruments, devices and components available on the market. For the development of real-time sound analysis software and of the Digital Signal Processing Workstation used in CIBRA activities, many tests have been made particularly to find sound boards and interfaces (PCI, PCMCG, USB, FireWire) suitable for the specific needs of each research. Many high quality sound acquisition boards are on the market to provide recording quality often better than DAT recorders. Several low-cost AD/DA boards are available for musical application and most of them can be used for sound acquisition. Nevertheless, not all of these equipment has enough acoustic quality or accuracy to be used in high quality recording and sound analysis. The board should be accurately selected to match the needs of the research and the quality level of the whole electroacoustic chain used. Choosing boards with both analogue and digital l/O is recommended.
