Types

type Resampler

type Resampler struct {
	MethodR                int               // MethodR is the method of resampling if needed. Default is 0 (no resampling)
	MethodRAdvancedConfigs interface{}       // MethodAdvancedConfigs is the method of advanced configs if needed
	SizeBuffer             int               // SizeBuffer is the size of the buffer used in the resampling process.Default is 1024
	InConfigs              sopro.AudioConfig // the source configuration
	OutConfigs             sopro.AudioConfig // the target configuration
	Verbose                bool              // if true, the resampling process will be verbose
}

func (*Resampler) Println

func (rs *Resampler) Println(items ...any)

Println prints the items if the transcoder is in verbose mode

func (*Resampler) Wav

func (rs *Resampler) Wav(in *sopro.In, out *sopro.Out) error
