Run fast and reliable listening tests with SenselabOnlineTM
Use SenselabOnlineTM to design and conduct recognised and standard-compliant listening tests in a fast, reliable, easy-to-use and time-saving way.
Web tool enables professional and efficient audio evaluation tests
The SenseLabOnlineTM web application includes solutions ranging from standard-compliant ITU-R test methods like MUSHRA to advanced, fully synchronised 4k audio/visual testing using VR headsets and multichannel loudspeaker reproduction. Available listening tests include double-blind experimentation, automatic or custom randomisation of stimuli, precise playback, optimised user interfaces, easy handling of assessors, setup of test sequences, and automatic statistical analysis of test data and assessor performance.
Use SenseLabOnlineTM for product development
Companies in the telecommunications, audio coding, headphones and loudspeakers and hearing aid industries often use SenseLab's web application as a tool to develop and refine products.
Easily connect and distribute tests
The application runs in a browser using either WebAudio (the newest web-based audio interface, which has been tested extensively to ensure high-quality audio reproduction) or via the proprietary advanced sound player with full hardware control over ASIO drivers. Once you have registered as a user of SenseLabOnlineTM, you can sign in and build a range of standard-compliant and custom listening tests.
Because the system is built to run in an HTML5 compatible browser, you can distribute a listening test across physical locations, pending internet connectivity). All data transformation is done in Secure Socket Layer (SSL), and the application is approved with industry-standard code signing certificates.

Technical specifications for SenseLabOnline
Sound player - pushing the limits for online testing
The sound player used by SenseLabOnline has been developed exclusively for SenseLabOnline to meet the high performance criteria specified in the international standards for audio evaluation testing.
As well as meeting high performance criteria the sound player runs exclusively via your web browser, meaning that no additional programs need to be installed in order to build or run tests.
A dedicated Audio/Video player is also available in an advanced version that ensures full control of hardware.

Automatic statistical analysis
SenseLabOnline has implemented automatic statistical analysis procedures. Any time during a test, you can get an instant and full statistical analysis, and see preliminary results.
The automatic routines check data quality and basic assumptions before proceeding to plotting of the results.
Basic analysis methods like 2-way Analysis of Variance (ANOVA), showing mean values with confidence intervals, plotting of interaction between experimental variables (etc.) are always included.
For more advanced test types e.g. tests with multiple test questions/attributes, you will get a complete overview of the results using multivariate data analysis methods, such as Principal Component Analysis (PCA), and Hierarchical Multiple Factorial Analysis (HMFA).
Current available statistical modules include:
- Analysis of Variance (ANOVA)
- TUKEY HSD
- Mean scores with confidence intervals
- Interaction plots
- Assessor feedback
- Assessor performance (eGauge)
- Hierarchical multiple factorial analysis (HMFA)
- Multi Dimensional Scaling (MDS)
- Factorial Analysis on Distance Tables (FADT)
- Check-All-That-Apply (CATA) analysis
- Density plots
- Spider/radar plots.
You will receive the results as jpg files, and have access to raw data file for all your experiments.
