ACPWorkbench Stereo Equalizer Tool

The ACPWorkbench Stereo Equalizer Tool is a program developed by Arylic for precise EQ control. This tool can adjust the loudness of specific audio frequencies to the listener's preferences and the acoustics of the environment, known as the frequency bands. For example, an equalizer allows you to raise the bass while listening to dance music, or add treble in a room that responds to low-frequency sounds.

Stereo Equalizer


Customize your Music

  • Jazz

  • Pop

  • EDM

  • Concert at your Home

    All you need is a Windows computer (Windows 7 or later) and you can have a concert-like musical experience at home. It also supports 3D surround sound (with the exception of the Up2stream Mini V3), Taking your listening experience to the next level.

  • 3D surround Sound

    A 3D audio effect is where a sound source is placed virtually anywhere in three-dimensional space, including behind, above or below the listener, and then Stereo speakers and other audio devices generate the music to give you a different musical experience.

  • Clean and Clutter-free Interface

    The design is simple and intuitive, so even if you're not a professional studio player, you'll be able to study it in a few minutes and start customizing your sound!

  • Precise EQ Control

    Even if the 4stream app already supports EQ Control, I don't think this is enough for your needs. With our ACPWorkbench Tool, you can adjust your EQ more precisely and permanently store your settings on every device. This means you can customize the sound differently for each device.

  • Gain Adjustment

    The environment is different for each person due to their subjectivity. Now you can adjust the volume level to your own requirements and be most comfortable. And you can also make different adjustments according to different audio sources such as I2S, USB sound card, SPIDIF IN, etc.

  • Comment se fait la liason entre le pc et un up2stream 2.1? Merci.
    Si vous souhaitez avoir une connexion directe pour diffuser de la musique à partir d'un PC, branchez l'alimentation sur AMP2.1 puis connectez l'AMP2.1 au PC à l'aide d'un câble micro USB.
    Votre PC doit le reconnaître comme une carte son externe, vous pouvez le choisir comme sortie audio pour votre PC.
