  • Chains – movement, sliding, impacts, and ratcheting across metal
  • Impacts – Collins axe, chains, hatchet, machete, rubber mallet
  • Scrapes – hatchet, machete, saws, squeaks, dryer tube – TONS of variation
  • Sawing (on metal) – hack saw, machete blade + saw

Heavy Metal! was recorded using a large metal car door and several stereo pairs of microphones. The amount of variation is almost insane (hence the ! in Heavy Metal!). I started off with banging the hell out of the door with a 4lb Collins axe, rubber mallet, hatchet (blade and flat side), machete, and even heavy-gauge chains. Next I turned to scraping the old door until my ears were on fire. It’s like 40 minutes of nails on chalkboard, except that it is metal bits scraping across a heavy metal door. There are grinding sounds, scratching sounds, harsh squeaking sounds – with varying lengths and intensities. I did my best to group similar sounds and lengths together so the user can grab one track and quickly audition several variations. Most of the scraping sounds were made with a jagged piece of old dryer tube.

Then I moved on to sawing sounds. I used a hacksaw and a double-sided machete with one side being a slicing blade, and the other being saw teeth. And finally I took some heavy-gauge chains and went to town again. This time I scraped and slid the chains across the door, and ratcheted the chains across various edges of the door.

One great thing about this library was the door itself. It created some pretty amazing resonances, and reverberations. And sometimes I hit the door so hard some of the old rust would come crumbling off of it. This had to be one of the most rewarding recording sessions since Glass Smash HD!

Recording Technique: Heavy Metal! was recorded using two different stereo microphone setups, simultaneously. It started as a side-by-side shoot-out, and led to the great idea of releasing both sets of recordings. The two sets of microphones were the RØDE NT4, and a matched pair of Schoeps CMC6U MK4gs. The NT4 is nice because it has two capsules in XY, attached to one body. The MK4g are fantastic microphones that I arranged into an XY using a small t-bar. Both sets were recorded to a Tascam HS-P82 8-track field recorder.

The files in this collection labeled with “NT4” were recorded with the RØDE NT4, and files labeled with “MK4” were recorded with the Schoeps CMC6U MK4gs. Example:

METLFric_Car Door Scrape, Stutter, Long, MK4_Fienup_HVYMETL.wav

METLFric_Car Door Scrape, Stutter, Long, NT4_Fienup_HVYMETL.wav

These two recordings were done at the same time with two different stereo pairs, though edited independently. Each pair of microphones captured noticeably different frequency response due to differing internal hardware, as well as differing arrangement to the source. This was an eye-opening experience, and the differing results are often quite dramatic. Most of the files in the collection were recorded with both sets. Occasionally both sets were too bulky, and blocked too much of the door, so there are some sounds recorded with one or the other, in which case they are not labeled by microphone. Check out the track list for more details.

This collection provides some new and interesting sounds, as well as a ton of variations so your soundtrack never gets old! All Soundopolis tracks include metadata tags so they are easy to find using any search engine. All tracks are delivered as 96k/24bit stereo .wav files. Collections come in easily downloadable zip files.



UCS Update: New purchases of Heavy Metal! come fully equipped with UCS metadata and filenames. Previously purchased copies can also be updated.

Soundminer Users: To update your old version to the new UCS metadata, create a new database, scan in your copy of the collection, change the "Manufacturer" metadata column to say 'Soundopolis' (without the quotes, and capitalize the first 'S'), select the "Database" dropdown menu, and select "Lookup Metadata from Cloud".  Once the metadata is done updating, you can select all of the files, right click on them, and select "Embed Selected".  NOTE: THIS WILL CHANGE THE FILE NAMES!!!  If this action will impact older projects that use these sounds, it is your responsibility to save a copy with the original filenames somewhere so as not to impact those projects.

Other Update Options: Below are two zip files.  One is a text file with all of the metadata generated by Soundminer.  The second is that same information in a Microsoft Excel spreadsheet.  These should help if you use a program other than Soundminer.  For directions on how to update your particular program, please consult with the manufacturer's website.  Soundopolis only uses Soundminer, and is not familiar with the metadata updating procedures of all of the other programs available.
