How to apply Bass effect programmatically in android

问题

I am trying to apply the Bass Effects programmatically by using the following code:

BassBoost bassBoost = new BassBoost(0, audioSessionId);
bassBoost.setEnabled(true);
BassBoost.Settings bassBoostSettingTemp =  bassBoost.getProperties();
BassBoost.Settings bassBoostSetting = new BassBoost.Settings(bassBoostSettingTemp.toString());
bassBoostSetting.strength = MAX_STRENGTH_FOR_BASS; // 1000
bassBoost.setProperties(bassBoostSetting);

bassBoost.setStrength((short) progress); // progress value from seek bar

But the bass effects aren't applied on the current audio session.
Please help me by showing me what's wrong.

回答1:

Check whether it is supported or not.

bassBoost = new BassBoost(0, 0);
bassBoost.setEnabled(true);

if (bassBoost.getStrengthSupported())
{
    short word1 = bassBoost.getRoundedStrength();
    bassBoost.setStrength(word1);
}

And you can also check that whatever you're testing on supports it (it is device-dependent). You can use:

final Descriptor[] effects = AudioEffect.queryEffects();

// Determine available/supported effects 
for (final Descriptor effect : effects) {
    Log.d(TAG, effect.name.toString() + ", type: " + effect.type.toString());
}
