Patent ID: 7346513

Claim:
An audio signal saving operation controlling method for causing an application program to simultaneously control a sending operation and a saving operation for an audio signal between a teacher computer and at least one student computer connected to a network, the application program being installed on the teacher computer and the student computer which are both equipped with a sound card, a record medium, and a network interface card, the method comprising the steps of: starting the sending operation for sending the audio signal from said student computer to the teacher computer via the network, when a send start method for starting the sending operation for said audio signal is called from the application program; stopping the sending operation for said audio signal from said student computer to the teacher computer, when a send stop method for stopping the sending operation for said audio signal is called from the application program; starting the saving operation for said audio signal to the record medium in the student computer, when a save start method for starting the saving operation for said audio signal to the record medium is called from the application program; and stopping the saving operation for said audio signal to the record medium in the student computer, when a save stop method for stopping the saving operation for said audio signal to the record medium is called from the application program, wherein said audio signal is saved to the record medium in the student computer without need to interrupt the sending operation for said audio signal from the student computer to the teacher computer, wherein said audio signal is sent from the student computer to the teacher computer without need to interrupt the saving operation for said audio signal to the record medium in the student computer, wherein an information file for a mixer device is automatically generated, and after it is generated, a user can customize the information file, and wherein the sending operation uses hybrid audio coding including a bark level calculating and quantizing circuit operable on a modified discrete transform of pitch from said audio signal to output a coefficient of a time axis that is obtained by a speech process and a coefficient of a frequency axis that is obtained by an audio process.
