In a previous blogpost we talked about the Opus codec, which offers very low bitrates. Another codec seeking to achieve even lower bitrates is Codec 2.

Codec 2 is designed for use with speech only, and although the bitrates are impressive the results aren’t as clear as Opus, as you can hear in the following audio examples. However, there is some interesting work being done with Codec 2 in combination with neural network (WaveNets) that is yielding great results.

Once in a while it is necessary to convert big audio or video archives to new formats and metadata conventions, other servers, new loudness targets or apply some audio processing/restoration algorithms.
Now we offer a managed processing of archives to companies and institutions, where we adapt our algorithms and workflows to special requirements of our clients, implement all steps (no need to program the Auphonic API yourself) and perform the whole process on dedicated hardware to speed-up the conversion.
