Functions ¶
func ContinuousPlay ¶
ContinuousPlay opens audio stream and plays raw pcm chunks, requesting ingoing channel. It's blocking function.
func ContinuousPlayOpus ¶
ContinuousPlayOpus opens audio stream and plays opus encoded chunks, requesting ingoing channel. It's a blocking function.
func ContinuousRecord ¶
ContinuousRecord records chunks and puts them into channel. It's a blocking function.
func ContinuousRecordOpus ¶
ContinuousRecordOpus records Opus encoded chunks and puts them into channel. It's a blocking function.
func DecodePayload ¶
DecodePayload converts base64 to []byte
func EncodePayload ¶
EncodePayload retruns the base64 encoding of input
func EncodePayloadToString ¶
EncodePayloadToString converts []byte to base64 string
func RecordWAVChunk ¶
Types ¶
type WAVInfo ¶
type WAVInfo struct {
Id [4]byte
Length int32
WavFmt [8]byte
Format int32
PCM int16
Channels int16
Freq int32
BytesPerSecond int32
BytesPerCapture int16
BitsPerSample int16
Data [4]byte
BytesInData int32
}
WAVInfo contains wav information
func GetWAVInfo ¶
GetWAVInfo gets information from wav chunk
