I tried using AVAudioSession and AVAudioPlayer to record and play sounds respectively but the sound volume is very low.

I tried putting volume value of AVAudioPlayer to 1.0 and more but didnt help much.

What could be my other options to record sound which can be loud enough to play back?

This code should be useful for you:

#import <AudioToolbox/AudioServices.h>

    UInt32 audioRouteOverride = kAudioSessionOverrideAudioRoute_Speaker;                
    AudioSessionSetProperty (kAudioSessionProperty_OverrideAudioRoute,          
                                 sizeof (audioRouteOverride),&audioRouteOverride);

It will increase volume. The functionality of the code is to convert the ordinary sound to speaker sound on ur iPhone. That's why kAudioSessionOverrideAudioRoute_Speaker is used.
