Sound-activated recording, transmission, and playback
First Claim
1. A method of transferring sound, comprising:
- (a) storing the sound in a buffer;
(b) monitoring one or more sound attributes of the sound for indications of presence of a sound segment in the sound;
(c) transferring the sound in the buffer when the one or more sound attributes produce an indication of sound segment presence; and
(d) transferring the sound after the indication.

Abstract
A method and apparatus for sound recording, transmission, and reproduction eliminate periods of silence and prevent cut off of the leading edges of the sound segments. A recorder stores the sound in a First-In-First-Out (FIFO) device while monitoring the attributes of the sound, such as sound intensity level. When the attributes indicate that the sound should be recorded, the recorder transfers the contents of the FIFO onto a recording medium, and proceeds to record the incoming sound on the medium. When the attributes of the incoming sound indicate that a period of silence has begun, the recorder stops recording the sound on the recording medium, and begins to store the sound in the FIFO.

10. A method of transferring incoming sound, comprising:
-
(a) storing the incoming sound in a buffer;
(b) monitoring one or more attributes of the incoming sound to produce indications of sound segment presence and effective sound absence based on the one or more attributes;
(c) transferring a predetermined interval of the sound in the buffer when the one or more sound attributes produce an indication of sound segment presence, the predetermined interval extending to a point in time when the indication is produced;
(d) transferring the sound following the indication; and
(e) terminating said step (d) when the one or more sound attributes produce an indication of effective sound absence. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A method of sound-activated transfer of incoming sound, the method comprising:
-
identifying non-overlapping segments of sound and effective sound absence within the incoming sound;
transferring the segments of sound; and
determining a first plurality of intervals within the segments of effective sound absence, each interval immediately preceding one of the segments of sound, each interval being part of and associated with a segment of effective sound absence, the plurality of intervals comprising at least one interval shorter than a segment of effective sound absence associated with said at least one interval; and
transferring the first plurality of intervals. - View Dependent Claims (22, 23, 24, 25, 26, 27)

28. A sound recorder, comprising:
-
an input receiving digitized waveforms representing sound;
a memory storing a program; and
a processor executing the program; and
an interface to a recording medium, the interface being coupled to the processor;
wherein;
the processor, under control of the program, determines sound segments within the digitized waveforms, causes the sound segments to be transferred through the interface to be recorded on the recording medium, and causes a plurality of intervals of the digitized waveforms to be transferred through the interface to be recorded on the recording medium, each interval immediately preceding one of the sound segments, at least one interval being shorter than time period between the sound segments immediately following and immediately preceding said at least one interval. - View Dependent Claims (29, 30, 31)

32. A wireless communication device, comprising:
-
a microphone receiving sound waves and generating electrical waveforms corresponding to the sound waves;
a converter coupled to the microphone to receive the electrical waveforms and convert the electrical waveforms into digitized representations of the sound waves;
a memory storing a program;
a processor executing the program, the processor being coupled to the converter to receive the digitized representations of the sound waves; and
a transmitter;
wherein the processor, under control of the program, (i) determines sound segments and effective silence periods within the digitized representations of the sound waves, (ii) determines a plurality of intervals within the effective silence periods, each interval immediately preceding one of the sound segments, and causes the transmitter to transmit the sound segments and the intervals, while not transmitting portions of the effective silence periods that are outside of the intervals. - View Dependent Claims (33)
