Features
Agora’s Voice Calling provides reliable, high-quality, real-time voice call capabilities that you can customize for your application.
Outstanding audio
Clear audio
The Agora Voice Calling SDK uses a 48 kHz sampling rate with full-sound bandwidth capture. It provides natural audio reproduction and ensures clear sound during the voice calls that matter most. Agora’s Real-Time Engagement Platform provides HD audio up to 192kbps (hardware limitations apply) supported by our in-house SOLO™ and NOVA™ audio codecs.
Background and surround sound
Include local background music, accompaniment, and sound effects along with voice for a more immersive user experience.
Seamless audio
Agora’s proprietary algorithms ensure consistent audio, free of stutters and jitters, even under challenging network conditions that may have up to 80% packet loss.
AI-powered noise cancellation
Using automatic echo cancellation, automatic gain control, automatic noise suppression, and an AI-powered noise cancellation algorithm, Agora’s platform adapts to variant acoustic conditions to remove ambient and distracting noises, ensuring voices come through crystal clear.
Creative possibilities
Voice effects
Make in-app voice calls fun and engaging using a variety of voice APIs that can add a range of special effects. From sound mixing to sound reverb, users can change the way their voices sound to match their moods, characters they’re playing, or just satisfy a whim.
Surround sound
Agora expands the traditional left and right stereo channels to deliver an enveloping 360 degrees of sound. Users can adjust the positioning and distance of the channel to create more immersive gaming, virtual-reality, or augmented-reality experiences.
Versatile controls
In-ear monitoring
Agora’s Real-Time Engagement Platform supports in-ear monitoring for mobile devices. Users can hear their own voices or voice effects in online KTV, live-streaming apps, and other apps where audio is important.
Active-speaker recognition
Agora’s AI algorithms analyze streaming data to identify and capture the active speaker.
Original streams processing
Export the original audio and video streams to process for other purposes.
Recording
Record live audio events on the cloud or on your premises. You control the audio format, path of storage, and voice quality.
