...e to convert this frame to G711. But when I use Speex UltraWideBand the Asterisk don't convert it. Then I need in my Asterisk Channel Source include the Speex Library in resample this frame in 32KHz to 8KHz. Searching for it in Speex Doc, I found it: SpeexResamplerState *resampler; resampler = speex_resampler_init(nb_channels, input_rate, output_rate, quality, &err); err = speex_resampler_process_int(resampler, channelID, in, &in_length, out, &out_length); But in my source I have one *dataframe where is my payload. How I can use it to resample my frame? Thanks you very much, Thiago. -----------...

Hi everyone, I recently began using libspeex 1.2 Beta 1 on Windows using MS Visual C++. I have gotten a decoder and an encoder to work fine from the excellent sample code posted at the website. But I face a problem. I am working on using Speex in a program to play and create audio books encoded using Speex (currently testing it only; for these tests, I do not use Ogg to save the encoded
