A Preliminary Study on Quality of Experience Assessment of Compressed Audio File Format

Audio compression formats reduce the file size before downloading and uploading on the Cloud and social media platforms. An audio codec performs this operation. The uncompressed or lossless format can become lossless and lossy compressed files shrinking file size due to compression. Uncompressed file format change not only decreases the original size but also cuts the audio quality. The bit rate also drops. One assesses the quality of experience (QoE) of compressed audio file formats by comparing them to the original audios. One needs to conduct subjective QoE assessment experiments of both formats. This can be done by uploading a compressed file on the Cloud depending on its quality and sample rate to determine the satisfaction level of the end-user and which audio quality can be uploaded on the cloud, including other social media platforms.
