Types ¶
type DecoderFloat32 ¶
type DecoderFloat32 struct {
// contains filtered or unexported fields
}
DecoderFloat32 decode the mp3 stream by minimp3
func NewDecoderFloat32 ¶
func NewDecoderFloat32(source io.Reader) *DecoderFloat32
NewDecoderFloat32 creates and returns a new mp3 decoder with the default internal buffer size.
func (*DecoderFloat32) Bitrate ¶
func (d *DecoderFloat32) Bitrate() int
Bitrate returns the mp3 bitrate of the last decoded frame. If no frames have been decoded yet, then it will return 0.
func (*DecoderFloat32) Channels ¶
func (d *DecoderFloat32) Channels() int
Channels returns the number of channels of the last decoded frame. If no frames have been decoded yet, then it will return 0.
func (*DecoderFloat32) Read ¶
func (d *DecoderFloat32) Read(p []float32) (int, error)
Read copies the decoded audio data from the internal buffer to p and returns the number of items copied. If the internal buffer is empty, then Read first tries to read mp3 data from the source and decode it. If len(p) == 0, then Read will return zero bytes, but if the internal buffer is empty, then before that it will still try to decode one frame and fill the internal buffer.
func (*DecoderFloat32) SampleRate ¶
func (d *DecoderFloat32) SampleRate() int
SampleRate returns the sample rate of the last decoded frame. If no frames have been decoded yet, then it will return 0.
func (*DecoderFloat32) Seek ¶
func (d *DecoderFloat32) Seek(offset int64, whence int) (int64, error)
Seek sets a new position for reading audio data. At least one decoded frame is required to set a new position. If there are no decoded frames, then Seek will return an error. The mp3 data source must support the io.Seeker interface. If the source doesn't support io.Seeker, then Seek will panic.
type DecoderInt16 ¶
type DecoderInt16 struct {
// contains filtered or unexported fields
}
DecoderInt16 decode the mp3 stream by minimp3
func NewDecoderInt16 ¶
func NewDecoderInt16(source io.Reader) *DecoderInt16
NewDecoderInt16 creates and returns a new mp3 decoder with the default internal buffer size.
func (*DecoderInt16) Bitrate ¶
func (d *DecoderInt16) Bitrate() int
Bitrate returns the mp3 bitrate of the last decoded frame. If no frames have been decoded yet, then it will return 0.
func (*DecoderInt16) Channels ¶
func (d *DecoderInt16) Channels() int
Channels returns the number of channels of the last decoded frame. If no frames have been decoded yet, then it will return 0.
func (*DecoderInt16) Read ¶
func (d *DecoderInt16) Read(p []int16) (int, error)
Read copies the decoded audio data from the internal buffer to p and returns the number of items copied. If the internal buffer is empty, then Read first tries to read mp3 data from the source and decode it. If len(p) == 0, then Read will return zero bytes, but if the internal buffer is empty, then before that it will still try to decode one frame and fill the internal buffer.
func (*DecoderInt16) SampleRate ¶
func (d *DecoderInt16) SampleRate() int
SampleRate returns the sample rate of the last decoded frame. If no frames have been decoded yet, then it will return 0.
func (*DecoderInt16) Seek ¶
func (d *DecoderInt16) Seek(offset int64, whence int) (int64, error)
Seek sets a new position for reading audio data. At least one decoded frame is required to set a new position. If there are no decoded frames, then Seek will return an error. The mp3 data source must support the io.Seeker interface. If the source doesn't support io.Seeker, then Seek will panic.
