Embodiment bis-
A kind of method that the embodiment of the present invention provides audio frequency to play, be applied to the electronic equipment that is provided with hard disk and audio output device, the portable electric appts such as such as notebook computer, hard disk herein specifically can refer to mechanical hard disk (or claiming non-solid state hard disc).The executive agent of the method can be preferably audio processing chip (as the process chip of sound card) or the CPU (Central Processing Unit, central processing unit) of electronic equipment.
Below in conjunction with concrete embodiment, the treatment scheme shown in Fig. 1 is described in detail, particular content can be as follows.
Step 101, obtains audio data frame to be played.
Wherein, audio data frame is the primitive that audio frequency is play, the voice data that each audio data frame is play for recording a time slot.For example, MP3 (a kind of audio format) file is made up of multiple audio data frames, and the audio stream in Streaming Media is also made up of multiple audio frames.Voice data in audio data frame specifically can comprise the voice data of corresponding multiple audio frequency frequencies, multiple audio frequency frequencies can be the space predeterminated frequency value in human auditory system frequency range multiple audio frequency frequencies (for example, human auditory system frequency range is generally 20-20000Hz, can start, at interval of 200Hz, an audio frequency frequency is set from 100Hz, between each audio frequency frequency, the frequency values at interval also can be unequal), the voice data of each audio frequency frequency can comprise volume value.Volume value can be dB (decibel) value, can be also the ratio value with respect to descant value.
Concrete, in the time carrying out audio frequency broadcasting, C P U or audio processing chip can obtain the each audio data frame in corresponding document or Streaming Media in order.
Step 102, reduces the volume value of voice data corresponding with pre-stored interference frequency in described audio data frame, obtains flat amount audio data frame after treatment.
Wherein, disturbing frequency is to carry out at audio output device the broadcasting frequency that exerts an influence larger to the message transmission rate of hard disk when audio frequency is play.Because different hard disks may there are differences at aspects such as shape, material, physical constructions, so interference frequency corresponding to different hard disks may be also different.A parameter disturbing frequency to can be used as hard disk is carried out record.And, disturbing frequency can be a frequency, (under this frequency, hard disk has maximum amplitude to the broadcasting frequency that exerts an influence maximum to the message transmission rate of hard disk, hard disk and audio output device have produced resonance), disturbing frequency can be also multiple frequencies, to the message transmission rate of the hard disk broadcasting frequency acquiring a certain degree that exerts an influence.Disturb the process of obtaining and storing of frequency can be described in detail in the back.
In this step, audio data frame being carried out to the processing of flat amount, can be that all audio data frames to playing in electronic equipment all carry out this processing.Certainly, preferably, the condition of carrying out this processing can be set, in the time satisfying condition, carry out again the processing of flat amount, so, the concrete implementation of this step can be: if the hard disk of electronic equipment is carrying out data transmission, reduce the volume value of voice data corresponding with pre-stored interference frequency in audio data frame, obtain flat amount audio data frame after treatment.
Like this, in the time of hard disk transmission data, the volume value of the corresponding voice data that disturbs frequency in audio data frame is reduced, then carry out follow-up audio frequency broadcasting, when reduction audio frequency is play the impact of hard disc data transmission, can reduce the damage of the audio frequency to playing.
In addition, if the hard disk of electronic equipment is not carrying out data transmission, can not carry out the processing of flat amount to this audio data frame, directly according to audio data frame to be played, carry out audio frequency broadcasting, voice data be carried out to normal play.Certainly, in this case, also can take other processing, to this, the embodiment of the present invention does not limit.
The above-mentioned condition of carrying out the processing of flat amount can further be specially: the hard disk of electronic equipment is carrying out data transmission, and the data file of transmission exceedes default capacity threshold (as 200M B).Be that executive condition is that hard disk is in the data transmission of carrying out big data quantity.
Preferably, if electronic equipment is provided with multiple hard disks, so pre-stored interference frequency can comprise the interference frequency of each hard disk in multiple hard disks, i.e. interference frequency corresponding to each hard disk in store electrons equipment.The interference frequency of each hard disk can be that a frequency can be also multiple frequencies, and pre-stored interference frequency can be the summation of the interference frequency of all hard disks.Like this, the concrete implementation of step 102 can be: if existed at the hard disk that carries out data transmission in each hard disk of electronic equipment, the volume value that reduces in audio data frame the voice data corresponding with the interference frequency of hard disk carrying out data transmission, obtains flat amount audio data frame after treatment.
In force, the method for the embodiment of the present invention can realize by corresponding application software is installed in electronic equipment, can record the interference frequency corresponding to hard disk of various models in this application software.Can also obtain the model of hard disk in current electronic device by this application software, and determine corresponding interference frequency.By this application software, can also obtain and record the duty of hard disk, in the time that hard disk starts to carry out data transmission, record this hard disk in transmission state, in the time of the DTD of hard disk, record this hard disk in non-transmission state.Like this, after getting audio data frame to be played, can carry out above-mentioned corresponding processing according to the duty of the hard disk of current record.
In the embodiment of the present invention, while carrying out the processing of step 102, concrete implementation can adopt the one in following several modes:
Mode one, reduces default numerical value by the volume value of voice data corresponding with pre-stored interference frequency in audio data frame, obtains flat amount audio data frame after treatment.
This processing mode, in audio data frame, all reduces identical default value by the volume value of voice data corresponding all interference frequencies, processes simply, can improve treatment effeciency, ensures the fluency that audio frequency is play.
Mode two, by the volume value of voice data corresponding with pre-stored interference frequency in described audio data frame, the volume value that exceedes default volume threshold is reduced to described default volume threshold, obtains flat amount audio data frame after treatment.
Concrete, in audio data frame, for each interference frequency, obtain the volume value that disturbs the voice data that frequency is corresponding, and judge whether this volume value exceedes default volume threshold, if exceed this volume threshold, this volume value is reduced to this volume threshold, otherwise can process.
This processing mode, for the lower voice data of volume, can carry out less change, even can not change, and under ensureing that audio frequency is play the prerequisite of the less impact of hard disc data transmission generation, has reduced to a great extent the damage of the audio frequency to playing.
Step 103, according to flat amount audio data frame after treatment, carries out audio frequency broadcasting.
Concrete, if the executive agent of this flow process is CPU, CPU can send to audio data frame after treatment flat amount audio processing chip (as the process chip of sound card) to carry out audio frequency broadcasting; If the executive agent of this flow process is audio processing chip, audio processing chip can carry out digital-to-analog conversion to flat amount audio data frame after treatment, sends to audio output device to carry out audio frequency broadcasting the simulating signal after conversion.
In the embodiment of the present invention, also provide the method for obtaining and storing of disturbing frequency, as shown in Figure 2, the treatment scheme of the method can comprise following step:
Step 201, at each audio frequency frequency, is used default volume value respectively, carries out the continuous audio frequency of single-frequency point and plays, and in the time that audio frequency is play continuously, obtain the message transmission rate of hard disk.Wherein, the continuous audio frequency of single-frequency point is play, the broadcasting sound of certain single-frequency being continued.
Concrete, in the time that each audio frequency frequency carries out continuous audio frequency broadcasting, can use identical default volume value.The method of obtaining the message transmission rate of hard disk can be, makes hard disk carry out the data transmission (as the copy of the file of larger capacity) of big data quantity, the data traffic of hard disc data port is measured simultaneously, and computational data transfer rate.The message transmission rate of obtaining can be preferably the average data transfer rate in Preset Time section (as 10 seconds), for example, draws average data transfer rate with the total data flow measuring in 10 seconds divided by 10.
Step 202, in the message transmission rate of the each audio frequency frequency of the correspondence of obtaining, exceedes the ratio reducing with respect to reference speed rate the audio frequency frequency corresponding to message transmission rate of default proportion threshold value, is stored as interference frequency.
Wherein, reference speed rate can be the maximum transmission rate (can be theoretic maximum transmission rate, can be also the maximum transmission rate that actual measurement draws) of hard disk, and reference speed rate can be the basic parameter of hard disk.
Concrete, first, for each message transmission rate of measuring and calculate at each audio frequency frequency in above-mentioned steps 201, can calculate each message transmission rate of obtaining ratio with respect to reference speed rate reduction.As shown in Figure 3, for the hard disk to certain model, by said method, the statistics schematic diagram of the ratio that the message transmission rate of obtaining at each audio frequency frequency reduces with respect to reference speed rate.Then,, by the above-mentioned ratio value calculating and default proportion threshold value comparison, for the ratio value that exceedes proportion threshold value, its corresponding audio frequency frequency can be stored as the interference frequency of this hard disk.
In addition, for step 202, also audio frequency the frequency corresponding message transmission rate that in the message transmission rate of each correspondence of obtaining audio frequency frequency, numerical value is minimum can be stored as to interference frequency.
In the embodiment of the present invention, in the time that the electronic equipment that is provided with hard disk and audio output device carries out audio frequency broadcasting, reduce the volume value of voice data corresponding with pre-stored interference frequency in audio data frame to be played, obtain flat amount audio data frame after treatment, then, according to flat amount audio data frame after treatment, carry out audio frequency broadcasting, like this, can reduce the amplitude of hard disk resonance in audio frequency playing process, thereby, can improve the job stability of hard disk in electronic equipment.
