UK artist and sound designer Robert Stevenson is the powerhouse behind Ahrdee, and his amazing Sound Effects keep rolling out and moving into our clients's productions around the world. From thumping heart beats to bleeping heart monitors, and Sci Fi Red Alerts of aliens on board, to noisy Submarine diving bells, Ahrdee's SFX are a must-have for your ER medical dramas or full-throttle action movies...
A deep synthesised heartbeat, with an alternate beat effect, speeding up from 60BPM to 138BPM in 60 seconds. Note: this recording can only be heard properly via speakers which can reproduce low frequencies. Humans,
A simulation of “ringing in ears” sound (tinnitus). Sometimes used after explosion or other loud sound effect. This sound will only be audible on devices which can reproduce high frequency sound. Humans, Annoyance
A loud alarm similar to, but not the same as, the Star Trek ‘Red Alert’ klaxon on the original Star Trek TV series. Note: this is not a sample lifted from a Star Trek sound track, it has been made from scratch, (synthesised), so there is no infringement of "Star Trek" copyright. Foley,
A (simulated) telecommunications sound of the type which accompanies text being displayed on screen in movies and TV shows. (#3), Computer, Text Display
A simulation of a thumping human heartbeat accelerating from 65 bpm to 166 bpm in 48 seconds with a simulated medical monitor (EKG) bleep on each beat. Uses samples of real human heartbeat. Humans,
An accurate simulation of the Greenwich Time Signal, a.k.a. “The Pips” used to mark the hour on BBC radio broadcasts. The six pip time signal is played six times, the takes are increasingly loud. Electronic,
A (simulated) telecommunications sound of the type which accompanies text being displayed on screen in movies and TV shows. (#4), Computer, Text Display
A synthesised heartbeat at 139 BPM with whooshing Doppler ultrasound-type effect. A simulation of baby's heartbeat in womb: foetal cardiac ultrasound. It could also be used for the sound of the pulse rushing in any artery not just heart. Humans,
Bleeps like those heard in radio communications with NASA astronauts.
Could also be used for other signals / alerts, e. g. medical monitor beep, or timer countdown. Electronic,
A synthesised, but natural sounding, heartbeat effect accelerating from 73bpm to 200bpm in 65 seconds, with subtle stereo reverberation. NB: this recording can only be heard properly on devices which can reproduce low frequencies. Humans,
Very bassy stereo rumble, like a rocket engine heard from inside a spacecraft.
Note this sound is only audible on devices which can reproduce low frequencies. Science Fiction,
A synthesised (not recorded) electronic warble sound somewhat similar to UK “trimphone” ring and UK phone ringing tone. A generic electronic telephone ring which could be used for a mobile telephone ringtone. Ringers Phones, Electronic phone ringers
A synthesised heartbeat at 53 BPM with whooshing Doppler ultrasound-type effect. The sound could also be used for the sound of the pulse rushing in any artery not just heart. Humans,
A deep synthesised heartbeat, with an alternate beat effect, speeding up from 66BPM to 184BPM in 34 seconds. Note: this recording can only be heard properly via speakers which can reproduce low frequencies. Humans,
Thirty five censor bleeps (1KHz plus 3rd harmonic) increasing in duration from 0.05 seconds to 2.5 seconds.
As used to replace swearing or other words which should not be broadcast, (e. g. names and addresses ). Electronic,
Alarm similar to, but not the same as, Star Trek ‘Red Alert’, (i. e. NOT taken from Star Trek sound track). This alarm sound could be used for any alarm, not necessarily science fiction. Science Fiction,
Simulation of alarm like that indicating leak of hazardous material, (e. g. radioactivity, biohazard, chemical), in a large building, (laboratory, factory, nuclear reactor). Could be used for any danger alarm (or novelty ring tone). Foley,
American man counts down from ten to zero, once per second, with intercom effect, and NASA-style tannoy (Public Address) echo effect. Two takes, second take has more echo-reverb. Talking, American / Male
Three pairs of materialize / de-materialize 'Transporter' sounds, somewhat similar to Star Trek TV series, last pair are deliberately distorted. Science Fiction,
Synthesised robotic heartbeat sounds at different speeds and pitches, (progressively slower and deeper). Designed for one beat sound to be selected from this group then looped at the desired rate. Humans,
An accurate recreation of the "static" hiss noise as heard on analogue TV or FM radio, (in wide stereo), similar to white noise, loopable. Electronic, White noise
Simple synthesised click sounds of increasing duration. Initially like dripping water hitting hard surface, then clock-like “tick”, then "snap", then “clack”, and finally a “tock” sound. Multimedia, Click sounds
An alarm sound similar to that used on NASA spacecraft / space-station. Could also be used as aircraft alarm or other alarm, (or novelty ring tone). Science Fiction,
Recreation of "hardware disconnect" from computer sound, e. g. when USB device is removed from computer. Could also be used for other computer alerts. Computer,
Countdown from ten to zero by monotone male robot voice with American accent, #1-4. Four versions: slightly different effects applies to each take. Talking, Computers / Male
