Duck Audio

[Dimple Belousson]

Inaudio engineering, ducking is an audio effect commonly used in radio and pop music, especially dance music. In ducking, the level of one audio signal is reduced by the presence of another signal. In radio this can typically be achieved by lowering (ducking) the volume of a secondary audio track when the primary track starts, and lifting the volume again when the primary track is finished. A typical use of this effect in a daily radio production routine is for creating a voice-over: a foreign language original sound is dubbed (and ducked) by a professional speaker reading the translation. Ducking becomes active as soon as the translation starts.

In music, the ducking effect is applied in more sophisticated ways where a signal's volume is delicately lowered by another signal's presence. Ducking here works through the use of a "side chain" gate. In other words, one track is made quieter (the ducked track) whenever another (the ducking track) gets louder. This may be done with a gate with its ducking function engaged or by a dedicated ducker.

Audio duck feature is buggy PA 905 UNI. whether turned on or off, if turned off it simply pause then resume after incoming notification which is okay. the problem is it doesn't lower the volume to distinguish notification coming specifically from messages instead it rocks along with music. ??

I've not noticed any significant differences in build 905 compared to previous builds as far as volume ducking for notifications goes. Are you use you haven't adjusted any of your output modes in the meantime?

no, just default values for output modes. this occurs in wired headset and Bluetooth connection. sometimes its working but audio duck is not good, it Lowers the volume but not significantly prioritizing the notification sound and somehow can't distinguishable and there are times that its not working-just no ducking effect.

okay heres my final verdict, duck volume mess with equalizer, and AAudio output but not with tones,stereo,limit,tempo and in terms of audio output, opensl and audiotrack outputs suits when equalizer is off.

I just did some tests with internal speaker and bluetooth headphones and it works fine - volume dips in order to play the notification sound. Obviously the comparative levels depends on what level you are listening to music at vs. your chosen notification volume.

However the same tests with a wired headset did seem incorrect. The notification sound did not play at all and the music volume did not dip - the only indicator that the notification had occurred was the phone's vibration effect. I tried several output methods (OpenSL ES, Hi-Res, and AAudio) and got the same result each time, with the EQ on or off. Could be related to the odd way Samsung routes notification sounds when using a wired headset (it can send the tones to the internal speaker, although it did not in this case).

So to clarify, this does not appear to be an issue that only occurred with Poweramp build 905 and it occurs with earlier builds too, and so it could be related to other system changes such as Android updates etc.

Ironically, while I was out walking at lunchtime and listening to a podcast on my wired headphones, I received a notification - and that time, both the audio ducking and the notification sound occurred correctly.

It sounds like your experience is about the same as I see. Volume ducking works correctly with Bluetooth (and, for me at least, on internal speakers) but not with wired headset. For me, DVC doesn't make any difference, but as it does on your device I would suggest you turn it off for your chosen Wired Headset/AUX output method.

@andrewilley with the speaker phone it does, with Bluetooth and wired headsets it no longer does. I don't know if it's for Android 11 but before I did, I was thinking of installing an older version of PA Let's see if i get it. sorry for my english is google translate

Hello!

Recently I used Audo Duck effect by Markus Meyer with a long sound track (audio track from a movie) and voice track (recorded spoken movie subtitles) to mix them both together. The effect was supposed to decrease volume of parts of sound track where voices were about to be mixed in. Most of the result was all right but some voices were not possible to understand because of the background sound still too loud.

Auto Duck effect reduces volume (amplitude) of audio track by choosen amount of decibels instead of reducing volume to a certain common level lower than voice segments if appropriate sound segments are too loud.

I would like to add another options in Auto Duck settings window:

There is a relatively easy workaround, as you could apply the Auto Duck effect multiple times to the parts that need greater level reduction.

This is obviously less convenient than being able to do it automatically, but it saves making the effect more complicated.

I have an announcer voice that comes in and ducks the games music track slightly so you can hear it properly, however the player has weapons and the sound of the bullets can drown out the announcer. I cant duck them using the Audio Mixer because the sounds are one shots played via script when the weapon is fired, am I able to duck them via script?

When it comes to producing audio content, there are a variety of techniques that a producer can use to help improve the quality of the audio signal or sound. If there are multiple audio sources then it is important to be able to balance those sources so that everything remains clear and easy to listen to.

After all, content creators want to ensure that what they have recorded sounds great. It could be music, spoken word, training videos, ambient sound, or anything else. You want it to come across in the best way possible.

Audio ducking is sometimes done by using compression, though it can also be done by a simple volume adjustment. Whichever method is used, though, the result is the same, which is that the audio signal on one track is made more distinct and clearer than the other.

Applying either a reduction in volume or compression can be done automatically or manually, but most digital audio workstations (DAWs) will allow you to do it automatically, and it greatly simplifies the process.

It doesn't have to be background music or music production - it can be speech, ambient sound, or anything else - it can be all of these or none. The important thing is that one of the audio sources is ducked to allow the other to remain clear and unimpeded.

Most DAWs or music production software will have some kind of facility for audio ducking. Though the specifics of the audio ducking will vary from software to software, the essence of using audio ducking remains the same.

When two tracks have been loaded, you can select the part of the track you want to apply audio ducking to or select all of both tracks (CTRL + A for Windows or CMD + A on Mac) to apply to the whole of the project.

You can then open the Audio Ducking control panel which will give you access to the settings you need to adjust. Again, the above example is from Adobe Audition, but the settings will be similar on most DAWs and video software, so this applies whether you are doing music production or editing videos.

Allows you to choose the type of sound you are ducking against. The icons represent speech, sound effects, ambiance, music, or to have untagged clips. You can choose either one type of content or as many as are relevant to the project you are working on.

This is a very important setting as this is where you choose the threshold of the ducking that will be applied to the background track. The greater the sensitivity, the greater the adjustments will be.

For example, if you select a middle-range setting on sensitivity, it will work well for having someone speak while reducing music volume, whereas a lower setting might be more appropriate for dealing with ambient sounds behind a presenter, and so on. You will learn how to do the volume decrease and return to the regular clip volume with practice.
