Variables ¶
var GarbageCollection = false
var TempDir = os.TempDir()
TempDir is where the temporary intermediate files are held
var TempPrefix = "sox"
TempPrefix is a unique indicator of the temporary files
var TempType = "wav"
TempType is the type of file to be generated (should be "wav")
Functions ¶
func ConvertToMatch ¶
func GetComment ¶
func MustFloat ¶
func MustFloat(t ...interface{}) float64
MustFloat returns only the first argument of any function, as a float
func MustString ¶
func MustString(t ...interface{}) string
MustString returns only the first argument of any function, as a string
func NumSamples ¶
NumSamples returns the number of samples in the file
func Paste ¶
func Paste(fname string, piece string, pasteStart float64, crossfade float64) (fname2 string, err error)
Paste pastes any piece into a place in the audio, assumes that the piece has "crossfade" length on both sides in addition to its current length.
func PostProcess ¶
PostProcess
func ResampleRate ¶
ResampleRate changes the sample rate and precision
func RetempoSpeed ¶
RetempoSpeed will change the tempo of the audio and pitch
func RetempoStretch ¶
RetempoStretch will change the tempo of the audio trying to keep pitch similar
func ReverseReverb ¶
ReverseReverb will reverse a piece, reverb it, reverse it back, and place it back in the position that the original note hits so it reverberates up to it.
func SampleRate ¶
SampleRate changes the sample rate
func SilenceAppend ¶
SilenceAppend appends silence to a file
func SilencePrepend ¶
SilencePrepend prepends silence to a file
func SilenceTrim ¶
SilenceTrim trims silence around a file
func SilenceTrimEnd ¶
SilenceTrimEnd trims silence from end of file
func SilenceTrimFront ¶
SilenceTrimFront trims silence from beginning of file
func Stutter ¶
func Stutter(fname string, stutter_length float64, pos_start float64, count float64, xfadePieceStutterGain ...float64) (fname2 string, err error)
Stutter does a stutter effect
