Summary

I want to launch commands with my voice using picovoice porcupine. On discord desktop the wakeword is not detected but on the mobile app it is. I tried recording the audio and the audio recorded from the mobile app is perfectly clear while the audio from the desktop app is distorted.

Reproduction Steps

    public async Task ReceiveHandler(VoiceNextConnection _, VoiceReceiveEventArgs args)
    {
        short[] frame = new short[porcupine.FrameLength];

        byte[] pcmData = args.PcmData.ToArray();

        short[] audioFrame = new short[pcmData.Length / sizeof(short)];
        Buffer.BlockCopy(pcmData, 0, audioFrame, 0, pcmData.Length);

        if (audioFrame.Length > porcupine.FrameLength)
        {
            int offset = audioFrame.Length - porcupine.FrameLength;

            for (int i = 0; i + porcupine.FrameLength <= audioFrame.Length; i += offset)
            {
                Array.Copy(audioFrame, i, frame, 0, porcupine.FrameLength);
            }
        }
        else
        {
            for (int i = 0; i < audioFrame.Length; i += porcupine.FrameLength)
            {
                int remaining = audioFrame.Length - i;
                Array.Copy(audioFrame, i, frame, 0, Math.Min(remaining, porcupine.FrameLength));

                if (remaining < porcupine.FrameLength)
                {
                    for (int j = remaining; j < porcupine.FrameLength; j++)
                    {
                        frame[j] = 0;
                    }
                }
            }
        }

        if (porcupine != null)
        {
            int keywordIndex = porcupine.Process(frame);
            if (keywordIndex >= 0)
            {
                await commandRoulette.RouletteStrat(commandContext);
            }
        }

        await Task.Yield();
    }
