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.
