Functions

func CreateCalibFiles

func CreateCalibFiles(ctx context.Context, soundCardID string, count uint) error

CreateCalibFiles creates CalibFiles.

func CreateRunTimeFile

func CreateRunTimeFile(ctx context.Context, soundCardID string, ts int64) error

CreateRunTimeFile create a RunTimeFile containing given unix time in secs.

func CreateStopTimeFile

func CreateStopTimeFile(ctx context.Context, ts int64) error

RemoveCalibFiles removes CalibFiles.

func VerifyCalibExist

func VerifyCalibExist(ctx context.Context, soundCardID string, count uint) error

VerifyCalibExist verifies calib* exist.

func VerifyCalibNotExist

func VerifyCalibNotExist(ctx context.Context, soundCardID string, count uint) error

VerifyCalibNotExist verifies calib* does not exist.

Types
