  1. Hello Everyone. If you are new to this, feel free to check out my original post - https://www.techspot.com/community/topics/opus-test.243617/.

    Without further ado, let's begin.


    First of all, here is the original FLAC file for reference:
    https://drive.google.com/file/d/1dTy50g2wDuf4Lz-wGr2_Bdkd9KYdb4cH/view

    Song used: People are Strange by The Doors.

    In this test, we will test 4 lossy audio codecs:
    AAC, MP3, OGG, and OPUS*.
    All audio 'samples' will be encoded in 5 bitrates of:
    48 kbps, 64 kbps, 128 kbps, 192 kbps, and 320 kbps.
    Every file of a certain bitrate has been sorted into folders.

    Which audio codec is which? Can your ears tell the difference?

    48 kbps: https://drive.google.com/drive/folders/1_QsPiN1do3HwAnpUV5ZKqInRMqPXXn_d

    64 kbps: https://drive.google.com/drive/folders/1INooCdo3PinBveLRMKmT6ALYV0kzuwRR

    128 kbps: https://drive.google.com/drive/folders/1CLBtRlri_Mkc4XsmIOl9fM1Gw_qjkiYA

    192 kbps: https://drive.google.com/drive/folders/1oNo01K2kzLRLZT1AJFT6kfydJKkAySiA

    320 kbps: https://drive.google.com/drive/folders/1pgex6ISS61DcGeRukHZ0U3w1906n2DuJ


    P.S.:

    1. Good quality headphones not required, but recommended for best audio listening experience.

    2. The answer will be available in approximately 3 months.

    3. Good luck! :)







    *opus re-samples audio from 44.1 kHz to 48 kHz.
