Speaker effect

Post by Giovani » Fri Nov 18, 2022 9:12 am

Hello.
Please, how to create in Audacity some speaker effect? I don't think on combo distortion, as You for example play distortion guitar. I think on effects for example, when You speak to microphone, or listen music from speaker. I don't know, if You understand me.
But, I don't know, how to do that?
Thank You.
Marco

You want it to sound like an overdriven guitar amp? The Distortion effect has several clipping and overdrive options. You can also the Graphic EQ effect to reduce the high & low frequencies.

And there are lots of 3rd-parts guitar amp "sims" (simulators) that people use when recording guitars direct (without an amp or microphone). Most sims are designed to sound like a particular guitar amp and some developers have a license to use the names of Fender or Marshall, etc., and in those cases I assume the real amp manufacturer has approved the software plug-in.

The microphone and the speaker each have their own characteristics which can be captured by Impulse responses: IRs.

There is a VST3 plugin from AudioThing called "speakers" which can combine the IRs of various microphones and speakers in combination ... https://www.audiothing.net/effects/speakers/
The free demo version of AudioThing's "Speakers" inserts silence every ~30 seconds, (that may be long enough for some jobs).

There are free plugins which will apply an IR to the audio track, but you have to find/create the IRs of the transducers/locations.

A free source of unusual IRs is ... https://fokkie.home.xs4all.nl/IR.htm
(old telephone handsets, jars, buckets, churches, abandoned factory buildings)

You'll need an IR loader plugin to apply Impulse Responses to audio.

If I have understood good lastly, impulse and response. So It is something, like convolution.
I don't know, if new Ladspa plugins works well in Windows version of Audacity. I remembered, that there is something, like this.
Also, I don't want distortion effect. I would like to create recording, when somebody listen for example music from the speaker, or somebody speaks into microphone. For example somebody has a concert and singer sings to theyr microphone or something, like this.

Sorry, that's confusing... If you are not listening live you are ALWAYS listening through a speaker (or headphones, etc.). ;) A high fidelity speaker is supposed to accurately reproduce the sound without any character of it's own. (Guitar speakers are not supposed to be high fidelity.)

Similarly, a microphone & PA system should ideally amplify the voice (or instrument) accurately, just making it louder. A music recording is supposed to sound like the real thing.... Well... not modern rock/pop/rap recordings. They are "studio creations".

Try the Graphic EQ effect. Maybe that's what you're after. Try cutting the frequencies below 500Hz by -6dB, and maybe the high frequencies above 3kHz. That can give an "old-time telephone" or "old-time radio" effect. If 6dB is not enough you can run it again with the same settings to knock the lows & highs down by another 6dB, and of course you can play with different frequency bands.

A modern cell phone doesn't seem to cut the highs noticeably but there is obviously no bass. (I'm talking about the tiny built-in speaker... The headphone output is full range and high fidelity.)

Note that cutting the highs will reduce the "T" &"S" sounds which can affect speech intelligibility, if that's important. So you might not want to over-do it on the high end.

And with EQ it's generally better to cut than boost ,because boosting digitally can push the levels into digital clipping (distortion).

There's a free 32-bit VST2 plugin called "Devicer" which has a "Club PA" setting, (#16).
It does sound like a large concert venue , (but it does not include microphone emulation: so too clean IMO)

There's Steve's "Public Address" plugin, but that's low-budget venue, like a small-club, (maybe too dirty) ...

Thank You for Your answers.
So, when I have analised those things, It is mainly based on some echoes, reverbs, or delays. So maybe I can use normal effects from Audacity, but those effects are also good.
