The audio processing method provided by the invention can be configured in computer equipment, and the computer equipment can be a central control system which is configured in a vehicle-mounted entertainment system. Fig. 1 is a flow chart of an audio processing method according to an embodiment of the present invention. As shown in fig. 1, the method includes the following steps S100 to S130.
S100, calculating the target audio length which can be identified by the target identification system, and confirming the audio length to be processed according to the target audio length.
In the embodiment of the invention, the recognition system refers to a system for recognizing voice, which is carried by the vehicle-mounted entertainment system and can be the vehicle-mounted entertainment system itself or an algorithm in the vehicle-mounted entertainment system. The audio lengths of different recognition systems are different, and different vehicle types are often configured with different recognition systems, and the target recognition system is the recognition system of the current vehicle type. It should be noted that the audio length of the voice audio is generally much longer than the audio length that can be recognized by the recognition system.
The audio in a vehicle is often of a large variety, such as ambient sounds, sounds during operation of the machine, or sounds of conversations of occupants in the vehicle. The vehicle-mounted entertainment system can acquire all the sounds in real time, process the acquired sounds, send the processed audio to the corresponding recognition system, recognize all the audio by the recognition system, extract control instructions, and return the control instructions to the vehicle-mounted entertainment system, so that the vehicle-mounted entertainment system can conveniently execute the control instructions. The target audio length is the audio length which can be identified by the target identification system, and the audio length which is obtained by the vehicle-mounted entertainment system is often larger than the target audio length and cannot be directly identified by the target identification system. Therefore, after the target audio length is determined, the audio length to be processed needs to be confirmed. The audio length to be processed is not necessarily the same as the target audio length, but the audio length to be processed has a certain commonality with the target audio length. For example, if the target audio length is 2048, the audio length to be processed may be 5120, 2048 and 5120 may have a plurality of common divisors, and an intermediate audio length corresponding to the common divisors may be set, through which the audio length to be processed is processed so as to be recognized by the target audio length. It should be noted that, the shortest audio length that can be supported by different vehicle-mounted entertainment systems is different, and often the shortest audio length is far greater than the target audio length, so the length of the audio to be processed cannot be set to be the same as the target audio length.
In some embodiments, for example, the step of calculating the target audio length that can be identified by the target identification system includes the steps of: and confirming the number of the audio channels, and calculating the target audio length according to the number of the audio channels.
In the embodiment of the invention, the specific calculation method of the target audio length of the target recognition system can be that the number of audio channels is confirmed according to the number of voice zones, and then the target audio length is calculated according to the number of audio channels. For example, for a vehicle model with a two-tone region, which includes four channels, namely, left mic, right mic, left ref, and right ref, the target audio length is 256×4x2=2048, and for a vehicle model with a four-tone region, which includes six channels, namely, left mic, right mic, left rear mic, right rear mic, left ref, and right ref, the target audio length is 256×6x2=4096.
In some embodiments, for example, in this embodiment, the step of confirming the length of audio to be processed according to the target audio length may include the following steps: judging the size of the target audio length and the shortest audio length which can be supported by the vehicle-mounted entertainment system; if the target audio length is smaller than the shortest audio length, creating a standard audio length according to a preset rule; and acquiring a data set of the audio to be identified according to the standard audio length to acquire the audio length to be processed.
In the embodiment of the invention, the shortest audio length supported by the vehicle-mounted entertainment system is generally longer than the target audio length, and in special cases, the shortest audio length supported by the vehicle-mounted entertainment system is shorter than the target audio length, and in such cases, the audio length to be processed can be directly set to be equal to the target audio length. If the shortest audio length that the vehicle entertainment system can support is longer than the target audio length, a standard audio length may be created according to a preset rule, where the preset rule may be to preset a plurality of values, such as a first value and a second value, in advance according to experience, and take the value higher than and closest to the shortest audio length as the standard audio length. After confirming the standard audio length, a data set may be obtained from the audio to be identified to obtain the audio length to be processed. The audio to be identified is all the audio acquired by the vehicle entertainment system, and the length of the audio to be processed is equal to that of the standard audio, wherein the difference is that the length of the audio to be processed is acquired from the audio to be identified.
S110, creating a plurality of storage containers adapting to the target audio length and the audio length to be processed according to the target audio length and the audio length to be processed, and storing all the storage containers into a buffer area.
In the embodiment of the present invention, the length of the audio to be processed is generally greater than the target audio length, for example, the length of the audio to be processed is 5120, the length of the target audio is 2048, a storage container with a data set length adapted to the length of the audio to be processed and the length of the target audio can be created, the length of the data set can be found from the common divisors in 5120 and 2048, the common divisors of 5120 and 2048 are 2, 4, 10, … … and 1024, and the maximum common divisors of 5120 and 2048 can be used as the length of the storage container, namely 1024. The number of the storage containers depends on the length of the audio to be processed, if the length of the audio to be processed is 5120 and the length of the storage containers is 1024, the number of the storage containers is 5, and all the storage containers are stored in the buffer zone, so that the audio to be processed is convenient to read. The buffer may be a ring buffer for storing data.
In some embodiments, for example, the step S110 may include the following steps: confirming the greatest common divisor of the target audio length and the audio length to be processed; and creating the storage containers according to the numerical value corresponding to the greatest common divisor, and confirming the number of the storage containers according to the multiple relation between the length of the audio to be processed and the greatest common divisor.
In the embodiment of the invention, the greatest common divisor of the target audio length and the audio length to be processed can be used as the length of the storage container. For example, the target audio length is 1024 and the audio length to be processed is 5120, then the greatest common divisor of the target audio length and the audio length to be processed is 1024, and a storage container for storing the data set is created with 1024 as the length. If the multiple relationship between the audio lengths 5120 and 1024 to be processed is 5 times, 5 storage containers can be created.
And S120, filling the data set corresponding to the audio length to be processed into all storage containers in the buffer area.
In the embodiment of the invention, the length and the number of the storage containers are matched with the length of the audio to be processed, so that all data sets of the audio length to be processed can be just stored in all the storage containers, and the subsequent reading is convenient.
In some embodiments, for example, the step S120 may include the following steps: confirming filling times according to the number of the storage containers; and filling the data set corresponding to the audio length to be processed into all storage containers in the buffer area successively according to the filling times.
In the embodiment of the present invention, if the length of the audio to be processed is 5120 and the length of the storage container is 1024, 5 storage containers are required, and when the data set of the audio length to be processed is filled into the storage containers in the buffer area, one storage container is filled at a time, and five times of filling are required. In addition, the buffer area can be internally provided with an available counter, and the counter is added with 1 for each filling, so that the filling times can be conveniently recorded, and the buffer area can also be provided with a readable counter, and the counter is added with 1 for each reading, so that the reading times can be conveniently recorded. It should be noted that when the data set is stored in the storage container in the buffer, the storage container can be read while the data is being filled, instead of reading after the data is completely filled. For example, there are 5 storage containers in the buffer area, wherein 3 storage containers are filled with data, and the reading requirement of the target recognition system is met, the data in the storage containers can be read and sent to the target recognition system, and meanwhile, the data set with the rest audio length to be processed can be continuously filled into the storage containers.
S130, reading the data set in the storage container from the buffer area according to the target audio length, and sending the read data set to a target recognition system as data to be recognized.
In the embodiment of the invention, when the data sets in the storage containers are read, the data sets are also sequentially read, for example, if the length of the storage container is 1024 and the target audio length is 2048, the data sets in two storage containers can be read from the buffer area each time and sent to the target recognition system, or the data sets in one storage container are read each time and sent after being read twice, so that the read data sets can be ensured to meet the reading requirement of the target recognition system. If the audio length to be processed is 5120, five data sets are in the buffer area, and after four storage containers are read, one storage container remains, and then a new data set can be waited for filling for reading and sending.
In some embodiments, for example, the step S130 may include the following steps: confirming the single reading number of the data set in the storage container read from the buffer area according to the multiple relation between the target audio length and the greatest common divisor; and successively reading the data set in the storage container from the buffer area according to the single reading number.
In the embodiment of the present invention, if the target audio length is 2048 and the greatest common divisor is 1024, the data sets in two storage containers can be read at a time, and if the target audio length is 4096 and the greatest common divisor is 1024, the data sets in four storage containers can be read at a time.
In some embodiments, for example the present embodiment, the audio processing method further includes the steps of: and if the new audio length to be processed is acquired, filling the data set corresponding to the new audio length to be processed into all the storage containers in the buffer area to cover the data set in the storage containers.
In the embodiment of the present invention, if the audio length of the audio to be identified is 20000 and the audio length to be processed is 5120, the data set can be obtained from the audio to be identified all the time, so as to continuously obtain the audio length to be processed, until the data set in the audio to be identified is completely obtained. When a new length of audio to be processed is obtained, the new length of audio to be processed is filled into a storage container within the buffer, thereby overwriting the old data set.
