Audio Bit Rate Mode
The bit rate mode determines wether or not the amount of data stored per second remains constant over time.
Why do we test it?
Contant bit rates means that the amount of data your device has to load every second remains the same. It's therefore more reliable on slow networks. Variable bit rates result in higher quality, but the data stream will not be contant. If bandwidth is not an issue, variable bit rates are generally preferred.

Audio Duration Detector
Verifying the audio duration is crucial to ensuring that the ad delivers its message clearly and effectively. If the audio is too long or too short, it may disrupt the user experience or fail to communicate the intended message. This test helps guarantee that the audio duration aligns with the visual, creating a smooth and engaging ad experience.
Audio Duration DetectorAudio Codec Detector
Choosing the correct codec is vital because not all browsers or devices support every codec. Testing the codec ensures compatibility, preventing playback issues that could affect user engagement with the ad. This validation helps avoid situations where audio fails to play correctly, leading to poor ad performance.
Audio Codec DetectorAudio Loudness Detector (LUFS)
Excessive loudness can irritate users, while audio that is too quiet may go unnoticed. The loudness test ensures that the ad's audio stays within acceptable loudness levels, preventing potential rejection from ad networks that enforce loudness standards. This helps to maintain consistency, ensuring your ad sounds professional and isn't disruptive to users.
Audio Loudness Detector (LUFS)Audio True Peak Detector
High peaks results in audio distortion, which can significantly detract from the user experience. This test ensures that the true peak level remains within an acceptable range, preventing distortion or other audio issues. Verifying true peak helps maintain the audio quality and ensures that the ad sounds professional.
Audio True Peak DetectorAudio Sample Rate Checker
The sample rate affects both the quality and file size of the audio. A higher sample rate typically produces better audio quality but increases the file size. This test ensures that the audio sample rate is appropriate for the ad, balancing quality and performance while maintaining compatibility across different platforms.
Audio Sample Rate CheckerAudio Channel Detector
Verifying the correct number of audio channels is critical to ensuring the creative functions as intended across devices and environments. Ads that incorrectly use multi-channel audio might experience compatibility issues or degrade the user experience. This test ensures the right audio channel configuration, optimizing for both performance and playback quality across platforms.
Audio Channel DetectorAudio Compression Detector
Optimizing audio compression ensures that the file size remains manageable without sacrificing audio quality. Over-compression can result in low-quality sound that could deter users, while under-compression may result in slower loading times. This test ensures that audio is adequately compressed to maintain a balance between quality and performance, which is vital for high-quality ad playback.

A higher bit rate typically results in better audio quality, but it also increases file size, which can slow down load times and affect ad performance. Ensuring the bit rate is optimized is crucial in balancing quality and loading efficiency. This test ensures the audio component of your ad maintains acceptable quality without negatively impacting performance or exceeding size limits.

Contant bit rates means that the amount of data your device has to load every second remains the same. It's therefore more reliable on slow networks. Variable bit rates result in higher quality, but the data stream will not be contant. If bandwidth is not an issue, variable bit rates are generally preferred.
Bit Rate Mode DetectorAudio File Extension Checker
An incorrect or unsupported file extension can result in playback errors or complete failure to load. This test ensures that the file extension is valid and appropriate for the ad, reducing the risk of errors and improving cross-platform compatibility. It's essential to have the right extension to avoid rejection from ad networks or issues during ad serving.
Audio File Extension CheckerAudio File Size Checker
File size has a direct impact on ad load times and overall user experience. Large files can lead to slow loading ads, increasing bounce rates and reducing user engagement. This test ensures that file sizes are optimized to strike the right balance between quality and performance, making ads faster and more efficient while avoiding penalties from ad networks that impose file size limits.
Audio File Size CheckerAudio Mime-Type Detector
Proper MIME-type detection ensures that the browser can correctly identify and play the audio in the ad. If the MIME-type is incorrect or missing, it may cause compatibility issues, where the audio fails to play, diminishing the ad's effectiveness.
