Sample Description

In CRI Atom, you can change the player parameters such as volume, playback pitch, filter cutoff frequency at the time of playback.

Each parameter can be modified before and while playing back the player.
Parameters are set to the player using specific parameter setting functions.
You must call the criAtomExPlayer_UpdateAll function on the player to apply the settings to the player.

Following is a code to set player parameters and apply low-pass filter.

CriAtomExPlayerHn player;
 
    /* Set volume */
    criAtomExPlayer_SetVolume(player, 1.0f);
    /* Set a pitch in cents */
    criAtomExPlayer_SetPitch(player, 0.0f);
    /* Set cutoff frequency for band pass filter */
    criAtomExPlayer_SetBandpassFilterParameters(player, 0.0f, 1.0f);
    /* Set biquad filter parameters */
    criAtomExPlayer_SetBiquadFilterParameters(player, CRIATOMEX_BIQUAD_FILTER_TYPE_LOWPASS, 1.0f, 0.0f, 1.0f);
    /* Apply parameters for all Voices used by the player */
    criAtomExPlayer_UpdateAll(player);
