The best field recorders for filmmaking have timecode support.įield recorders come in many different sizes which often correspond to weight. Instead, your DAW will automatically sync audio and video perfectly. The most common form of timecode displays hours, minutes, seconds and frames on a linear display in hh:mm:ss:ff format or as an alphanumeric string such as “00:00:01” (hour 00 minute 01 second).įor audio, timecode is used to synchronize multiple devices and media (both audio and video) on a metadata level.Īlthough many members of the production process use and make reference to timecode, it's particularly useful for editors and those who work in post-production.ĭuring post-production, timecode is a major time-saver.īecause both audio and video will have timecoded frames in their metadata, you do not have to manually sync audio and video. It was developed in 1967 for film production by EECO, an electronics company that developed video recorders, to keep track of individual shots when there were multiple cameras filming at the same time. 3 power approaches: externally powered, internal UN38.Timecode is a system of measuring time by dividing time into frames.Pricing can be viewed on the Abyssens official website. The storage capacity is in line with the autonomy of each model and therefore goes up to 16 TB for the largest and an optional external temperature sensor is available for all of our models.Īn online configurator called “ How to choose my underwater acoustic recorder” is available for determining the most suitable model. In addition to these previous applications, the high-frequency version allows the detection of clicks from marine mammals, including harbor porpoises, with a dedicated and optimized sampling rate of 360 ksps. The low-frequency version is commonly used to monitor ambient noise, vocalizations of marine mammals, and noise from ships or sea works. The target frequency range is divided into two categories for all models: low frequency (up to 30 kHz with an HTI96 MIN Low-Noise hydrophone) and high frequency (up to 200 kHz with an HTI99UHF hydrophone). The hydrophone is either integrated directly into the recorder or external. Thanks to a self-noise level below sea state zero and a high dynamic range, ambient noise can be monitored together with high level sources. A software-selectable analog high-pass filter can help for high-energy sites. wav format and have a high dynamic range of 110 dB that can be adjusted as a result of software-configurable analog amplification gains. It can also be used as a wired observatory.Īll models record 24 bits of raw data on. It is designed to be integrated aboard vehicles such as ROVs, AUVs, or gliders, owing to its very small size. This model is powered by an external source and does not have an internal battery. The XS version is a model specially dedicated to complement other platforms. These sessions consist of about 15 days (for the S model), three months (for the M model), to long-term monitoring of about six months (for the L model) of continuous recording. DORI is a modular line of underwater acoustic recorders which are made for short listening sessions for deployments at sea.
