Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is elaborated.
See also Fig. 1, Fig. 1 is the whole tone of the present invention schematic flow sheet of passage dynamic tuning method first embodiment frequently, and said method comprises:
Step 101 makes intelligent terminal receive the instruction that starts multimedia application one audio-frequency function, starts multimedia application according to this instruction that starts audio-frequency function;
Step 102 after multimedia application starts, makes intelligent terminal receive the instruction that startup audio frequency dynamic tuning is used, and the instruction of using according to startup audio frequency dynamic tuning starts the application of audio frequency dynamic tuning;
Step 103; Regulate a gain in the voice-grade channel in the application of audio frequency dynamic tuning; Voice-grade channel during dynamic tuning is used is corresponding one by one with audio-frequency function, and each voice-grade channel comprises that all analog digitals with this voice-grade channel corresponding audio function gain;
Traditional voice-grade channel is to divide according to the input and output audio frequency apparatus, can't the audio frequency effect of various multimedia application be transferred to the best.At present, though multimedia application is countless, their audio-frequency function is fixed; In audio tunning, the voice-grade channel among the CP (communication processor, communication processor) is fixing dead, can not revise flexibly, but the voice-grade channel resource that audio frequency codec (coder) has is very abundant, can the flexible configuration voice-grade channel.Therefore, the embodiment of the invention is repartitioned voice-grade channel in audio frequency codec, so that the audio frequency effect of various multimedia application is transferred to the best.In the embodiment of the invention, voice-grade channel is in audio frequency codec, to divide with audio-frequency function, compatible all multimedia application.This audio-frequency function comprises: recording, broadcast, conversation or audio frequency loopback (winding), also consider its earphone, speaker (loud speaker) and hand-held mode simultaneously for these audio-frequency functions.Wherein, the corresponding audio-frequency function of a voice-grade channel among the audio frequency codec, and each voice-grade channel all comprises all analog digitals gains with this voice-grade channel corresponding audio function.
Step 104 is updated to audio codec register and outside power amplifier register with a gain in the voice-grade channel after regulating, thereby upgrades in the multimedia application and audio frequency effect this voice-grade channel corresponding audio function.
In the embodiment of the invention, use whole tone frequently passage dynamic tuning method carry out audio tunning, need the software and hardware acting in conjunction, below set forth content and the workflow thereof that hardware comprises in detail.As shown in Figure 2; Fig. 2 is the voice communication hardware block diagram that whole tone frequency passage dynamic tuning method first embodiment of the present invention is adopted; As shown in the figure; Intelligent terminal hardware comprises: CP, AP (application processor, application processor), audio codec, audio frequency amplifier (power amplifier) and input output device (audio frequency input-output equipment).
Whole audio data path is made up of several sections shown in Figure 2, wherein, passes through the USB interface transmission of digital signals between AP and the CP; Pass through I2S (Inter-IC Sound between AP and the audio frequency codec; The audio data transmission bus standard) transmission high-fidelity HIFI (High Fidelity) signal; Through PCM (Pulse-code modulation, pulse code modulation) interface transferring voice (voice) signal; Audio frequency codec is transferred to audio frequency power amplifier with the signal that receives, and audio frequency power amplifier enlarges signal, sounds through audio frequency input-output equipment then.
