INTRO.

In 220A, my favorite part of the course was building the hydrophone and recording whale sounds in Monterey. To that end, I was inspired to take this experience a few steps further for my final. I microsampled my 7 minute whale recording from our boat ride to Monterey on October 14th, and used the raw audio material to construct drums, synthesizers and bass tones. This project will culminate in a larger independent study for next quarter at CCRMA!

Let's start by listening to my hydrophone recording from Oct 14th, 2021 here:

Whale sounds exist between 500-1000 Hz based on the recordings I have from Monterey.

MICROSAMPLING.

I use the process of microsampling to create snares, kicks, hats, synths, bass tones and more by repurposing audio material into a form that can then be edited into something else.

  • Let's take my 7 minute hydrophone whale recording from Monterey as an example. First, I started by listening to the sample and identifying about 10 different clips within the sample that contained whale sounds I'd like to microsample.

  • I then cleaned them up by EQing and shortening them, and placed them on their own tracks in Ableton Live.

  • Then, I opened up Simpler and Sampler, which are two tools in Live, to be able to crop the samples to about 200-300 milisecond clips.

  • By playing them on loop repeatedly, you end up with sound material that can be tuned into a key. I tune the microsample to C so that I know where I am starting from. From there, this microsample can be sculpted into a sample of my choosing, thus forming the early stage basic elements of a producer sound pack.

    BEATMAKING.

    Here are some of the whale samples, and the sounds I sculpted from them:

  • Whale Sample 1: and 2: were used to create a drone:

  • Whale Sample 3: and 4: were used to create a set of hi-hats:

  • Whale Sample 5: was used to create a synth:

  • Whale Sample 6: and 7: were used to create more hi-hats:

  • Whale Sample 8: was used to create a kick:

  • And whale sample 9: was used to create a snare:

  • END RESULT.

    And here is the final beat!

    Thank you to the incredible teaching team Chris Chafe, Nick Virzi, Clara Allison and Barbara Nerness and to our class for an awesome quarter! See you in 2022!


    PROJECT PROPOSAL.

    Winter Quarter.

    Sound MANA Volume 2: 100% Organically Sourced Nature Field Recordings from Under Water

    In 220A, my favorite part of the course was building the hydrophone and recording whale sounds in Monterey. To that end, I was inspired to start researching more opportunities to be able to record marine life and animals underwater, to serve as Sound MANA Volume 2. I started my research at the end of the fall quarter, and the project will continue as an independent study into the winter quarter at Stanford CCRMA. The long term project now will be to provide a nature sound pack from all 4 elements: Earth, Water, Air and Fire. We may have to go to space next!

    BACKGROUND.

    soundmana1

    Last year, I spent two weeks in a forest in Woodstock, NY field recording nature sounds from streams, rocks, mushrooms, bark, sticks, rusted metal and leaves. The idea was to collect as much raw audio material sourced from nature as possible, to then sculpt into recognizable production one-hits like snares, kicks, hi-hats, and toms, or create virtual instruments like chord, bass or drone synthesizers. While there are many packs available full of raw nature field recordings, few go the extra step to sculpt and process these sounds into usable production files that sound like comparable drums or electronic instruments in the industry.

    soundmana2

    Taking this a step further, I am very interested in the power of music to heal and uplift, therefore changing the planet and making the world a better place by connecting directly with the individual. Lyrics, for example, have the power to uplift or oppress - we can be singing back to ourselves lyrics that give us more life, or that keep us constricted and stuck, perpetuating stereotypes or ideas that hold us back from joy, potential or growth. Beyond lyrics, I started asking myself the question, how else might we contribute to the sounds we hear being uplifting, organic...healthy even! In the same way consumers are waking up to asking questions about their food sources - wondering if the food is organic, non-GMO, pesticide free etc...we currently lack a conversation in the music industry about where our beats come from! My intention with Sound MANA (music, art, nature, awareness) Volume 1 was to create an offering of useful production sound tools that were all made and sculpted from organic nature field recordings. To that end, the very sonic material you as the producer would be creating with has a purity to it, a sonic naturalness to it, a richness in depth and sound. This is very unique and takes a lot of work, providing enormous value to the consumer of the pack and the industry of music creators at large.

    You can see an interview I did with Splice about this very topic here.

    In June 2021, my collaborators and I released the pack on Splice.com, and in November 2021, we were awarded the New.Wav award, for innovation and boundary-pushing in the music industry.

    RESEARCH.

    For this project, I have spoken to:

  • Diva Amon, Marine Biologist, Welcome to Earth National Geographic
  • Sasha Leitman, CCRMA
  • Chris Chafe, CCRMA
  • Nick Virzi, CCRMA
  • Adam Partridge, Ableton Certified Instructor, Producer, Collaborator, Sound MANA Co-Founder
  • En Wong, Educator, Collaborator, Sound MANA Co-Founder
  • Izzy Medina, Splice, Pack Creation and Field Recording Specialist
  • Logan Smith, Bahamas Boat Captain, Marine Life Specialist
  • EXAMPLE. Exumas Cay, Bahamas.

    I also went out to the Bahamas during Thanksgiving Break and recorded the sound of Dolphins under water as well. The Bahamas are home to enmorous amounts of underwater research and development, including the premise for the new National Geographic piece "Welcome To Earth", for which I attended the screening in Los Angeles in December.

    In the winter quarter, I will speak to:

  • Hopkins Marine Biology Center
  • Aquarium of the Pacific
  • Ocean Bloom at the Dome, Downtown Los Angeles
  • John Chowning, CCRMA
  • And explore the idea of visiting:

  • Maui
  • North Shore of Oahu
  • Pier 39 San Francisco, CA Seals
  • Monterey
  • Antarctica
  • Research Materials Include:

  • Among Whales book
  • Welcome To Earth series
  • The Lonliest Whale film
  • Whale Song film
  • Whale Music film
  • Fathom documentary
  • Paul Stretch - stretching audio samples infinitely to create desirable drone effects. More here.
  • PLAN.

    The plan forward is to create a few more hydrophones, research the best underwater recording gear options, and travel to be able to record sounds from under water marine life as well as aquatic above ground animals. I'd like to record whales, dolphins, seals, seagulls, waves crashing, as well as research and identify reef and under water animals that make loud noises. Then I would travel to those places to collect sound, or collaborate remotely with others who are local to see if they can capture audio for me. From there, I treat the audio, clean it up, and start sculpting the raw audio into drum hits, synths, effects and loops!

    PROCESS.

  • Prep and record field recordings
  • Collect and label all samples
  • Import samples into Izotope Rx and isolate animal marine sounds by activating spectral de-noise, isolated desired frequency, re-normalize to bring volumes up, de-click, EQ, reverb, compression. Look for glissando shapes in the spectrogram
  • Provide users with these raw, cleaned up and isolated field recordings, but also start to make synths, drum sets, drones etc
  • Build beats and loops with individual set of one off hits
  • Work with my collaborator and Splice to finalize the pack
  • Create a demo piece for Splice listeners
  • Release pack, present to Stanford CCRMA
  • DELIVERABLES.

    Final deliverables would include a pack to be handed off to Splice.com for commercial release. The research and final sonic composition materials would be presented to my advisor and perhaps shared at a future CCRMA Colloquium or 220A class!
