安卓：在通话过程中发送声音给别人？ [英] Android: Transmit sound to somebody during a call?

问题描述

我上下打量了SDK这一点，但我无法找到任何东西。我不知道是否有传送声音的方式，如WAV或OGG，一个电话，这样在另一端的人能听到它时。 （这种声音可能，可另听到，不到位，正常的语音传输。）是否有我可能忽略了一个可能性？

I've looked up and down the SDK for this, but I can't find anything. I'm wondering if there's a way to transmit a sound, such as a WAV or OGG, during a call such that the person on the other end can hear it. (This sound should be heard in addition to, not in place of, the normal voice transmission.) Is there a possibility I may have overlooked?

推荐答案

没有，对不起 - Android应用程序必须将通话中的音频流的访问权限。现在，如果用户有手机免提模式，我想你玩噪音的喇叭可能会被麦克风拾取，当然质量是马马虎虎。

No, sorry -- Android applications have no access to the in-call audio stream. Now, if the user has the phone in speakerphone mode, I think noises you play on the speaker might be picked up by the microphone, but of course the quality is so-so.
