Slight tangent, but does anyone have experience with recording hydrophones in excess of 192khz? Last I checked, most of these are specialty devices with high price tags.
Recording full-fidelity whale or dolphin sounds (amongst others) requires using a higher sample rate than is available in most consumer-grade equipment. There's a lot more information down there!
- hecanjog 10mo agoI've used audiomoths for this. They can be configured to record at sampling rates up to 384kHz and be deployed with waterproof cases: https://www.openacousticdevices.info/audiomoth https://www.openacousticdevices.info/audiomoth
- DoctorOetker 10mo agoWhy not use the ADC's used for CIS (contact image sensors, the linear sensors in consumer-grade scanners / photocopiers)? For example: 12 MHz (i.e. 12 000 kHz) sample rate per channel, 4 channels, 16 bit ADC: https://www.akm.com/eu/en/products/mfp-lbp/ak8471vn/ https://www.akm.com/eu/en/products/mfp-lbp/ak8471vn/ single digit dollar unit prices: https://octopart.com/search?q=AK8471VN¤cy=USD&specs=0 https://octopart.com/search?q=AK8471VN¤cy=USD&specs=0
