Audio Multiband Equalizer
Whether your products are web or IoT based, OTTStreamingVideo can design and build an audio equalizer with the exact number of frequency bands with the center frequency and bandwith parameters you need.
Our custom audio equalizers allow the user to change the response of each frequency band on the fly, i.e. while the music or other audio program is being live streamed or played back. Equalization can also be applied on input for recording.
Custom presets can be defined for your application (e.g. Flat, Bass Only, Bass Boost, and Loud).

Remote Work Tools
Until recently many companies were reluctant to encourage, or allow, people to work remotely. This may be partly due to a lack of experience managing projects with remote workers. It also may be partly due to a unfounded concern that since remote workers do not sit at a desk that can be seen by management, remote workers may not be as productive as people in the office.
