Audio quality testing
Gain actionable insights into your solution's audio quality across codecs, bitrates, devices, and network conditions. Benchmark against competitors to understand strengths and weaknesses. Optimize based on real and objective data, not on gut feeling.
Trusted by Startups, SMEs and Enterprise businesses worldwide
We can help
Achieve audio excellence
To match different use cases, we offer three different audio quality services, starting from one-time audits and ongoing testing activities to competitive analysis and benchmarking.
Testing
See how your solution’s audio quality changes and performs under various conditions. Our specialized audio labs and innovative testing tools allow us to simulate real-world scenarios, measuring performance across diverse network environments and device configurations.
Echo cancellation and noise suppression
Echo cancellation and noise suppression is key to clear audio communication. We simulate various conditions, like room sizes, speaker setups, and background noise, to assess how well apps reduce echoes and remove unwanted noise.

Compare audio quality against industry standards and competitors using our competitive analysis and benchmarking services. Identify strengths and weaknesses and use the data to innovate and improve.
Audit
Evaluate the audio quality of your solution. See how it performs under different conditions, like changes to network and device configurations, and find out how it compares to competitors.
Get brief insights into:
- Your app's audio performance
- How your app stacks against competition
Approach
Full and no-reference audio evaluation
Evaluate audio quality and gain actionable insights using our flexible approach, tailored to the specific needs of your project. Set your product apart and set your growth in motion.
Full-reference evaluation
Use full-reference audio evaluation to compare your audio against the original file to precisely identify degradations during compression, transmission, and playback. This approach is ideal for lab-based diagnostic testing.
- Diagnose issues like packet drops, changes in frequency responses, distortions, and parameter misconfigurations
- Quantify quality degradations by comparing to a reference
- Test advanced features like echo cancellation and noise suppression
No-reference evaluation
Assess perceived audio quality without needing the original source files, which is useful when references are unavailable or when human perception is a priority.
- Analyze distortion, dynamics, loudness, and clipping
- Evaluate real-time audio where reference is unavailable
- Conduct large-scale analysis of real user data
- Monitor live services and user experiences
- Identify quality issues affecting users
