Any change of adding multistream?

Thanks

Hello,

I am trying to use Opus.NET to convert from an OGG with Opus data into a WAV file.

My OGG data originates from the Firefox MediaReader API, which records audio from the computer's microphone. Here is a sample data URL. I transmit this data URL to my server, and I decode it into a byte array as follows.

// `recording` is the data URL string
var base64 = recording.Substring(1 + recording.IndexOf(","));
var bytes = Convert.FromBase64String(base64);
var decoder = OpusDecoder.Create(48000, 1);
int len = this.inputBytes.Length;
this.wavBytes = decoder.Decode(this.inputBytes, len, out len);

The base 64 decoding works fine. However, when the code gets to the decoder.Decode line, it throws the following exception:

Decoding failed - InvalidPacket

I have two questions:

1. What is the best way to pass a data URL to the OpusDecoder such that the OpusDecoder will accept it?
2. Once the OpusDecoder is formed, how do you save it as a WAV file?

Thanks in advance!

I am having trouble running the demo in the VS2015 debugger -- and forgive me as I am still new to C# and this is my first time back in the programmer's chair in 15 years, so I'm sure I must be missing something obvious -- but:

The demo is throwing a "DLL not found" exception in the wrapper even though I am (almost) certain the DLL is correctly placed as everything was unzipped "as-was."

I'm running Win10 on a 64-bit system, but don't think this could be the issue. Any help appreciated as without it I cannot utilize the encoder.

Looks good, but can't get it to work when compiled for x64.

It seems that there isnt a .net opus port. Are there any plans for it ?

There is new version available: https://www.opus-codec.org/downloads/

Hello, trying to set 2 channels audio discontinuos

I changed the demo code from this

        _encoder = OpusEncoder.Create(48000, 1, FragLabs.Audio.Codecs.Opus.Application.Voip);
        _encoder.Bitrate = 8192;
        _decoder = OpusDecoder.Create(48000, 1);

to this

        _encoder = OpusEncoder.Create(48000, 2, FragLabs.Audio.Codecs.Opus.Application.Audio);
        _encoder.Bitrate = 8192;
        _decoder = OpusDecoder.Create(48000, 2);

The result was choppy audio I have experimented with bitrates and other options with the same resut

My audio input is confirmed as stereo .. mono works perfectly
