The most successful answer to this question is dependent on the accuracy with which the device generated the audio recording.
Creating exemplar samples can help compare a known sample with an unknown recording to see if it is a reliable representation. This is done using authentication methods.
Our tools use sophisticated mathematics to evaluate the signal to noise ratio of recordings and reduce unwanted sounds. They also isolate the wanted sounds and boost them while preserving the original recordings without altering them.
Our team has done investigations about sounds suspected of harming people or being a nuisance. Our experts, who are audio engineers, use SPL (sound pressure level) measurements to see if the sound meets OSHA standards.
Usually, audio and video signals can be synchronized if they are recorded at a similar rate. In many cases, it is also necessary to confirm the time of each recording.
