8 assessed work items are mapped below. Use the lesson title or activity ID to find the work, the evidence to keep, and the criteria used to assess it.
Suggested learner fit
Education catalog title: Shaping Your Sound with EQ, Compression and Gates — Mixing Elective
About 16–18 after a first mix; experienced younger learners may take it with guidance.
Priority skills: EQ, compression and gating chosen for a musical reason; level-matched A/B checks.
Prior skills: Can compare a passage at matched level and restore an unprocessed reference.
Equipment: ArtistPro studio, supplied session, UNIQUEL-IZER and D1 examples, headphones.
Expected time: Plan 8–12 hours for eight lessons and labs.
Teacher guidance: Teacher edition required for school use; review processing choices by ear.
MU:Re9.1.T.Ia · National Core Arts Standards — Music Technology Judge a musical result
Assignment
Open the raw plugin-demo session and listen to 00:45–01:00 at a comfortable level. Write one musical goal for Vocal before opening an effect. Try a small fader change first, then restore it. Decide whether the problem remains. Choose EQ for a tonal problem or D1 for a dynamic problem, changing only one processor at a time. Record the passage, setting, comparison level, and one possible drawback.
Evidence to keep
Name the musical aim and two listening criteria. Mark the exact passage supporting your decision; explain one benefit and one cost of the chosen version.
Assessment criteria
Name the musical purpose, compare the same passage fairly, and support the decision with audible details.

2. Read an EQ curve
MU:Re9.1.T.Ia · National Core Arts Standards — Music Technology Judge a musical result
Assignment
Select Vocal → UNIQUEL-IZER → Open existing plugin settings. Enable the processor. Use one Parametric band at 350 Hz, −3 dB, bandwidth 1 octave; leave other bands flat. Compare the embedded original and EQ examples, then reproduce the comparison in the studio. Change only bandwidth, then only frequency, returning to the reference setting each time. Write which change affected body, which affected clarity, and whether either helped in the full mix.

3. Create space without thinning the mix
MU:Re9.1.T.Ia · National Core Arts Standards — Music Technology Judge a musical result
Assignment
Listen to Bass and Drums together, then add Rhodes and Vocal. State which part becomes harder to hear and identify the moment. Use UNIQUEL-IZER on one competing track with a broad cut of no more than a few decibels as a first test. Match level and compare the whole passage. Restore the original if the mix loses more than it gains. Check a quieter section and record whether a static setting still works.

4. Understand compression
MU:Re9.1.T.Ia · National Core Arts Standards — Music Technology Judge a musical result
Assignment
Disable EQ and microphone modeling. Open D1 on Vocal and leave automatic gain and limiter off. Set ratio 4:1, attack 20 ms, release 150 ms. Lower threshold until the louder phrases produce useful reduction. Compare bypassed and active versions at similar perceived level using output gain. Explain which parts became more consistent and which details became more exposed. Calculate the ideal output increment for a signal 8 dB above threshold at 4:1, then explain why real transients may differ.

5. Shape attack and release
MU:Re9.1.T.Ia · National Core Arts Standards — Music Technology Judge a musical result
Assignment
Play the original, fast-attack, and slow-attack vocal examples one at a time. Describe consonant onset and sustain separately. Do not use loudness as the only description. Reproduce the two attack settings on Vocal, holding ratio, threshold, and release fixed. Try a shorter and longer release around the 150 ms starting point and listen to phrase endings. On Drums, test gently and note whether cymbal decay moves with louder hits; restore the source afterward.

6. Use gates and expanders musically
MU:Re9.1.T.Ia · National Core Arts Standards — Music Technology Judge a musical result
Assignment
Open Street Life — plugin demo, select Vocal, solo it and use 00:45–01:00 with recording disarmed. Add D4 from the plug-in library. Set two active zones and boundaries 3/4/5 to −60/−36/0 dB. Set output-map offset −24 dB, zone 3 ratio 0.5 and zone 4 ratio 1; enable ZGC. Keep input/output gain 0, automatic gain off and limiter off. Keep both active-zone attack controls at 10 ms and release at 200 ms. Compare bypassed and active playback without changing other processing. Identify one quiet wanted event, explain whether it survived, and save your settings and comparison notes.

7. Control the detector
MU:Re9.1.T.Ia · National Core Arts Standards — Music Technology Judge a musical result
Assignment
Select the same Street Life Vocal passage and add or reset D4. Set one active zone with −24/0 dB input boundaries, ratio 4, attack 10 ms, release 200 ms and map offset 0; automatic gain, limiter and ZGC off. Open KEY and compare the program output with all key filters off. Set filter 1 to High pass, 180 Hz, shape 0.24; enable it and replay the same passage. Keep audition Off. Explain why the reduction changes even though the filter is in the detector rather than directly in the audible path.

8. Build and evaluate a processing chain
MU:Re9.1.T.Ia · National Core Arts Standards — Music Technology Judge a musical result
Assignment
State one tonal goal and one dynamic goal for Vocal, Drums, or Bass. Create the smallest useful UNIQUEL-IZER/D1 chain and compare it at matched listening level. Compare EQ before compression with EQ after compression if your host supports reordering. Otherwise, draw the two chains and explain how the compressor would respond to each. Check a second passage and the full mix for clipping, pumping, lost attacks, and lost endings. Submit your analysis, including why you used or declined expansion, and take the knowledge assessment.

Some relevant work is present, but the intended result has not been demonstrated.
0
The required evidence has not been submitted or demonstrated.
Record each criterion and the next action. Practical equipment work needs an observed demonstration. Use the course grading plan for the final result.
Self-guided completion
Read the evidence requirement before starting. Save the work, check each criterion and revise any missing or unsuccessful part. Use a peer or instructor for tasks that require feedback or a witnessed practical demonstration.
