The invention relates to a signal processing method and device. The signal processing method comprises the steps: calling an internal recording port of a terminal, acquiring internal recording signals, wherein the internal recording signals comprise sound played at the terminal; carrying out echo silencing processing on a microphone signal of the terminal based on the internal recording signal, wherein the microphone signal is sound collected by a microphone of the terminal; mixing the internal recording signal and the microphone signal after echo silencing processing to obtain a first sound mixing signal; and transmitting the first sound mixing signal to an external device. 本公开关于一种信号处理方法及装置。信号处理方法包括：调用终端的内录接口，获取内录信号，其中，内录信号包括在终端播放的声音；基于内录信号对终端的麦克风信号进行回声消音处理，其中，麦克风信号为通过终端的麦克风采集到的声音；将内录信号和回声消音处理后的麦克风信号进行混合，得到第一混音信号；将第一混音信号发送到外部装置。
