Provide example reading from file

[carolinasolfernandez]

It would be great to have an example reading from a file. I'm trying to make it work without luck

Current code

        reader, _ := wave.NewReader(mediaFile)
	tracks := []kvm.TrackEntry{
		{
			TrackNumber: 1,
			TrackUID:    123,
			TrackType:   2,
			CodecID:     "A_CID",
			Name:        "TEST",
		},
	}
	pro, err := manager.Provider(kvm.StreamName(streamName), tracks)
	if err != nil {
		log.Fatal(err)
	}

	w, err := pro.PutMedia()
	if err != nil {
		log.Fatal(err)
	}
	go func() {
		for {
			fe, err := w.ReadResponse()
			if err != nil {
				log.Println(err)
				return
			}
			log.Printf("response: %+v", *fe)
		}
	}()

	chunk := reader.FmtChunk
	channel := uint64(chunk.Data.Channel)
	samplesPerSec := chunk.Data.SamplesPerSec

	t := uint64(0)

	for {
		d, _ := reader.ReadRawSample()

		data := &kvm.BlockWithBaseTimecode{
			Timecode: t,
			Block: ebml.Block{
				TrackNumber: channel,
				Timecode:    0,
				Keyframe:    true,
				Lacing:      ebml.LacingNo,
				Data:        [][]byte{d},
			},
		}
		if err := w.Write(data); err != nil {
			log.Println(err)
		}
		t += 1000000 / uint64(samplesPerSec) //useconds per sample
		
		if reader.NumSamples == reader.ReadSampleNum {
			break
		}
	}

I'm getting noise when reading so I'm not sure whats' wrong
