Las Vegas, Nevada – France Telecom’s over-the-top service/app Libon uses SILK as its HD voice codec for client-to-client calls. Part of the mystery behind the use of SILK was due to political considerations.
Libon wanted to use the best available codec, according to a company source, but one camp within France Telecom wanted to the independent start-up group to use AMR-WB. The group was initially reluctant to talk about the use of SILK because it didn’t want to trigger another discussion about AMR-WB vs. SILK.
