声场信息提取算法的研究与实现

Research and Application of Information Extraction Algorithms in Sound Field

声场环境影响声音的重放质量,如果声场参数可以测量出来并应用于声音重放,将可以改善声音重放效果。研究一种声场信息提取的算法,并设计一款用于测量声学参数的运行在Android客户端的声学参数测量软件。软件主要包含录音模块、脉冲响应求解模块、频率响应求解模块、混响时间求解模块四大模块,具有较强的实用价值。

Sound field environmental impact the playback quality of the program. Therefore,the sound field information can be obtained by measuring the reproduction and applied to improve the playback quality. Studies the main sound field information extraction algorithm, using MLS sequence of room to measure impulse response. The software mainly includes 4 modules： the recording module, the impulse response module, the frequency response module, the reverberation time module, which has strong practical value.
