Abstract

A method for recording a plurality of audio files, which can be played individually and, at least in pairs, synchronously and which can be modified individually with respect to playing parameters, said method being implemented by means of electronic processing hardware and software means, including: —at least two independent devices originating sound signals, comprising storage means or a microphone input or an in line input; —means for playing audio files, and—software means for playing one or more audio files individually or synchronously, wherein (step 101) at least two independent audio files are acquired in real time and simultaneously, from at least two sound signal sources, and (step 102) they are synchronized one another by means of an encoder that encodes said same files, making them of the same time duration, obtaining at least two audio files of the same length and independent from one another, and said audio files are included in a respective container file, which is provided with related identification and operating parameters, and wherein (step 103) said at least two audio files are played, by means of said means for playing said synchronized audio files, simultaneously or independently with respect to one another, according to the instructions present in said container file provided with parameters.

Claims

1. A method for recording a plurality of audio files, which can be played individually and, at least in pairs, synchronously and which can be modified individually with respect to playing parameters, said method being implemented by means of electronic processing hardware and software means, including:

at least two independent devices originating sound signals, comprising storage means or a microphone input or an in line in input;

means for playing audio files, and

software means for playing one or more audio files individually or synchronously,

characterized in that

(step 101) at least two independent audio files are acquired in real time and simultaneously, from at least two sound signal sources, and

(step 102) they are synchronized one another by means of an encoder that encodes said same files, making them of the same time duration, obtaining at least two audio files of the same length and independent from one another, and said audio files are included in a respective container file, which is provided with related identification and operating parameters,

and in that (step 103) said at least two audio files are played, by means of said means for playing said synchronized audio files, simultaneously or independently with respect to one another, according to the instructions present in said container file provided with parameters.

2. The method according to claim 1, wherein acquisition of said at least two audio files takes place analogically by means of a microphone input or an in line input, characterized in that said analog signals are converted into digital signals by means of encoding of PCM>

44100 hz 16 bit stereo type, obtaining respective files in .WAV format.

3. The method according to claim 1, characterized in that synchronization of one of said at least two audio files is performed by means of encoding of PCM 44100 hz>

16 bit stereo type.

4. The method according to claim 3, characterized in that said encoding is performed by means of the following process:

Encode Start (filename, “

output.wav”

, ENCODE PCM, NULL, >

0);

Play (filename,

     0);

// start the file playing &

encoding.

5. The method according to claim 1, characterized in that it also comprises the step of subsequently acquiring one or more further audio files, synchronized and independent.

6. The method according to claim 1, also implemented by means of:

hardware and software means for acquiring video files, in real time;

hardware and software means for playing video files,

characterized in that it comprises the further steps of;

acquiring at least one video file;

synchronizing said at least one video file by means of encoding, obtaining a plurality of video and audio files of the same length, independent from and synchronized with one another;

playing, by means of said means for playing, said synchronized audio files and video files, simultaneously to or independently from one another, according to the instructions present in said parameters file.

7. The method according to claim 1, also implemented by means of:

hardware and software means including storage means in which image and/or text files with different extension are stored;

output means for playing images and/or texts with different extension,

characterized in that it comprises the further steps of;

acquiring from said storage means at least one image and/or text file;

synchronizing said at least one image and/or text file by means of encoding, with respect to said synchronized audio files and/or video files;

playing, by means of said means for playing said image and/or said text files, said synchronized audio and/or said video files, simultaneously or independently with respect to one another, according to the instructions present in said parameters file.

8. The method according to claim 1, characterized in that it also comprises the step of subsequently modifying, individually or simultaneously, one or more of said files comprised in said container file, by means of instructions present in said parameters file.

9. The method according to claim 1, characterized in that said encoding is performed by sampling.

10. A method for recording a plurality of audio files, which can be played individually and, at least in pairs, synchronously and which can be modified individually with respect to playing parameters, said method being implemented by electronic processing hardware and software, including:

at least two independent devices originating sound signals, comprising storage or a microphone input or an in line in input;

an audio file player, and

software for playing one or more audio files individually or synchronously,

characterized in that

(step 101) at least two independent audio files are acquired in real time and simultaneously, from at least two sound signal sources, and

(step 102) they are synchronized with one another by an encoder that encodes said same files, making them of the same time duration, obtaining at least two audio files of the same length and independent from one another, and said audio files are included in a respective container file, which is provided with related identification and operating parameters,

and in that (step 103) said at least two audio files are played by said audio file player, simultaneously or independently with respect to one another, according to the instructions present in said container file provided with parameters.
