I’ve been researching how to achieve a recording playback effect in iOS similar to the hands-free calling effect in the system’s phone app. How can this be implemented? I tried using the voice chat recording method, but found that the volume of the speaker output is too low. How should this issue be addressed? I couldn’t find a suitable API. Could you provide me with some documentation or sample code? Thank you.
Why is the volume very low when using the real-time recording and playback feature with AEC?
Hello @deicn, thank you for your post. Perhaps the output is low because it is coming out of the receiver and not the speakers? Please see defaultToSpeaker for more information. The Using voice processing sample code project is a good starting point to understand the relevant technologies.
