Abstract
The utility model relates to a digital sound effect device with recording function, which comprises a digital signal processor (3), a single chip (6), a memory for recording aural signal (8), wherein, the input/output end of the memory (8) is connected with the input/output end of the single chip (6). The utility model is provided with the memory for recording aural signal, under the management of singlechip, the signal after the treating of digital processor is stored in the memory to make the effect device with recording function.
Description
Technical field
The utility model relates to audio frequency effect device, particularly has DSP (digital signal processing) digital effecter.
Background technology
Effect device is the device that is used for applying effect, influence to audio frequency, all uses it when present many musical instruments (as electric guitar, string music etc.) performance and voice performance, we can say that effect device in the formation of music, has been absolutely necessary.
Existing effect device (as the DSP digital effecter) comprising: musical instrument input interface, D and D/A converter, DSP digital signal processor, single-chip microcomputer, audio output interface.Its principle of work is: the simulating signal that musical instrument sends is entered by input interface, sends into the DSP digital signal processor after analog to digital conversion.After in DSP, signal being carried out the mathematics manipulation computing, result's (digital signal) is become simulated audio signal through digital-to-analog conversion, export through audio output interface.Single-chip microcomputer is finished and is shown and the man-machine interface operation.
Existing effect device does not possess the function of recording and read-write external data.When needing recording, record signal, use outside sound pick-up outfit (as MD etc.) recording, use very inconvenient.
Summary of the invention
One of technical problem to be solved in the utility model is: a kind of digital effecter with sound-recording function is provided.
Two of technical problem to be solved in the utility model is: a kind of digital effecter that can read and write external data is provided.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
Digital effecter with sound-recording function, it comprises digital signal processor, single-chip microcomputer, is used for the storer of recording voice signal, and the I/O end of storer is connected with the I/O end of single-chip microcomputer.
In the such scheme, effect device also comprises the Card Reader seat, and the I/O end of Card Reader seat is connected with the I/O end of digital signal processor and/or single-chip microcomputer.
In the such scheme, effect device also comprises USB interface, and the I/O end of USB interface is connected with the I/O end of digital signal processor.
Compared with prior art, the utility model effect device has the following advantages:
1, has the storer that is used for the recording voice signal, can under the management of single-chip microcomputer, will through the signal storage after the digital signal processor processes in storer, make effect device have sound-recording function.
2, have Card Reader seat, USB interface, read-write external device data.

Embodiment
The utility model effect device embodiment as shown in Figure 1, 2, it is a digital recording specialty DSP digital effecter (Digita1Recorder of Professional DSP EFFECT).Effect device comprises digital signal processor 3, single-chip microcomputer 6, is used for the storer 8 of recording voice signal, Card Reader seat 5, usb 10, audio output interface 1, musical instrument input interface 9, D and D/A converter 2, keyboard 4, LCD display device 7, the I/O end of storer 8 is connected with the I/O end of single-chip microcomputer 6, the I/O end of Card Reader seat 5 is connected with the I/O end of digital signal processor 3 and single-chip microcomputer 6, and the I/O end of usb 10 is connected with the I/O end of digital signal processor 3.
The utility model effect device embodiment, its storer 8 adopts NAND FLASH storer, and Card Reader seat 5 adopts SD CARD Card Reader seat, adopts standard communications protocol SPI between digital signal processor 3 and the single-chip microcomputer 6; Storer 8, Card Reader seat 5, usb 10 are finished solid-state record, playback, storage and the dump to signal.
The principle of work of the utility model effect device embodiment is: simulating signal is entered by musical instrument input interface 9, after D and D/A converter 2 (CODEC) carries out analog to digital conversion, follows standard audio format, sends into DSP digital signal processor 3.In digital signal processor 3, signal is carried out the mathematics manipulation computing.Signal processing results can enter following two approach to the record of signal under the management of single-chip microcomputer 6: 1, single-chip microcomputer 6 is by the SPI communications protocol, from digital signal processor 3 picked up signal; Through file organization, signal is saved in the storer 8.By user instruction, preserve and can be compression or unpacked format.2, the signal in the digital signal processor 3 is followed SD CARD communications protocol through after the file organization, directly is sent among the SD CARD in the Card Reader seat 5 and preserves.Reset then is an inverse process: 1, single-chip microcomputer 6 form reading of data when depositing in from storer 8, and be sent to digital signal processor 3, through D and D/A converter 2, audio output interface 1 output audio signal.2, digital signal processor 3 form when depositing in from the SD CARD of Card Reader seat 5 reads signal data, through D and D/A converter 2, audio output interface 1 output audio signal.The dump of signal is divided into two approach: 1, Card Reader seat 5 (SD CARD) is pluggable physical module, is inserted into the storage signal that can directly read in other equipment in the card.2, pass through usb 10, directly the storage signal in external unit (this equipment must be the device of following usb protocol) transmission storer 8.
The utility model effect device embodiment, use 5 effects of Card Reader seat to be:
1, can directly read and move specific external effects algorithm routine;
2, can directly use algorithm data;
3, direct result of use voice data under the management of single-chip microcomputer 6, is followed SD CARD communications protocol, finishes:
A, from SD CARD, read the certain effects algorithm routine, move this external program then, produce certain effects;
B, from SD CARD, read the certain effects algorithm data, be loaded into inside then, use for program;
C, from SD CARD, read the certain effects voice data, be loaded into inner the broadcast then.
The utility model effect device, the I/O end of its Card Reader seat 5 can only be connected with the I/O end of digital signal processor 3, also can only be connected with the I/O end of single-chip microcomputer 6.
