how to make it sound like a telephone call?

Has anyone got any good tips for making an audio track sound like it was recorded over the telephone? I use audacity for recording dramas, and this is a frequent need.

TIA

See here: viewtopic.php?f=28&t=8227&p=33202&hilit=telephone#p33202

Another method: viewtopic.php?f=28&t=6768&p=26937&hilit=+telephone#p26937

The second method is a bit more complicated, but once it is set up you can reuse the effect any time you like.

I believe there is also a Nyquist plug-in that does the same thing.

What is this thing you call a "telephone?" You mean a cellphone or mobile? Those have way different sound problems.

True. The examples given in my first post are approximations to the sound from a land line.

What is this thing you call a "Land Line?" Oh, wait. That's how my DSL gets here.

So that's the challenge. How do you simulate gargling echoes that come and go?

On the other hand, this could be a Traditional Holdover. Like everybody knows that radar goes round and round and a newsroom has to sound like a TeleType machine. Neither has been used since 1970.

"Land-line"; a term commonly used in the UK for a wired telephone (as opposed to "cell phone" / "mobile phone" / "internet voip phone" / "string and tin can" ....

Quite so. In dramatic productions it is more important to create the effect that people will allow the audience to immediately draw the intended associations rather than the a totally accurate representation that may not evoke the desired response.

Given the audience is over 25.

I am trying to make the podcast I'm doing sound like it's a conversation between a person a landline and a person a cell phone. I read the posts above and do not understand what effect I should add or alter to make it sound like a phone conversation.

Please help.

Land-line telephones have a pinched quality because they're not high-fidelity services. It's just enough quality to get the voice to go through. Cellphones on the other hand have compression damage, packet loss, and fades.

You get to do both, you lucky dog. This is a sample of high MP3 compression. You can float in and out of this effect (done with actual MP3 exports) to get the cellphone effect.

If you're producing a theatrical presentation, the trick is to have the appropriate effect for the person you can't see -- the person filtered by his/her phone. So while Jane's talking and on camera, Fred's voice will sound like a cellphone. While Fred is talking and on camera, Jane's voice will sound like a muffled, pinched telephone.

I've seen it done where the scene is an establishing shot outside the builting or a long shot of the city and they both sound like they're filtered.

Are you asking step by step instructions for each of these effects? Have you ever used any of the Audacity effects? How long have you been using Audacity?

first band limit the audio to 300-4000cps
start rolling off the bass at 300
roll off the high end from 3000 up

that gives you a good phone sound with speaker
if you want bad phone sound then
add noise, echo, crosstalk, etc.

set the mike across the room when you record and sound like you are far away andor in a barrel (depending on room characteristics)

i would go for the good phone sound with perhaps a very little hiss added if necessary

note that bad phone sound is rare so dont overdo it
