Virtual classes with music: mixing audio

Introduction

Video conferencing works great for virtual meetings where one person talks at a time. But when trying to teach with music in the background (i.e. dance class), several problems arise. The music quality becomes garbled as it is played over a speaker and then re-recorded through another microphone. The music can drown out the voice of teacher.  Zoom has a feature to share computer audio, but the music can cut out when the microphone detects voice. The purpose of this tutorial is to mix both the instructor's voice and the music digitally so that both may be heard clearly.

This tutorial is for Windows devices. If you use Apple products, see 
https://www.youtube.com/watch?v=cdtuNrfXeEA . While this tutorial uses Zoom, the audio mixing will still apply to other video services, e.g. Skype.

I am not an audio expert--I just couldn't find any other instructions so I thought I would put something out there. Comments welcome.

Setup

Equipment

  1. A Windows laptop with camera will work, however a separate USB Webcam is recommended so that the camera can be positioned independent of the laptop.
  2. While any Bluetooth headphones with microphone may work, it is recommended to have a headset with a microphone that extends in front of the instructor's mouth.

Initial Setup

Headset

Pair your headset in Bluetooth or connect via USB. Make sure your headset works. Can you listen to music from your laptop/PC?

VoiceMeeter Banana

  1. Install Voicemeeter Banana: https://www.vb-audio.com/Voicemeeter/banana.htm . 
  2. Reboot
  3. Open Voicemeeter Banana
  4. Right click "Hardware Input 1" and rename to "Mic". Press enter. Left click "Mic". Select the name of the microphone of your headset. Preferably, choose the one with the prefix WDM. Click the A and B buttons in the Mic column so that only "B1" is lit up green and all others are dark.
  5. For the Hardware Input 2 and Hardware Input 3 columns, deselect all the A and B buttons, and click Mute.
  6. Right click Voicemeeter VAIO and rename "Music". Only A1 and B1 should be enabled.
  7. Right click Voicemeeter AUX and rename "Zoom". Enable only A1.
  8. Left click the A1 next to HARDWARE OUT. Select the name of your headset speaker. Preferably, choose the one with the prefix WDM.
  9. Left click the volume icon in the lower right of the task bar. Click the arrow on the left and then select VoiceMeeter Input.

Sound Calibration 

Calibrate the audio levels. Play music using your player, e.g. Spotify.  Adjust the following levels in Voicemeeter Banana:
  • MASTER SECTION A1 slider: overall volume for your headset
  • Mic slider: volume of your microphone. Temporarily enable the Mic A1 to hear your own voice. Don't forget to turn it off when done calibrating.
  • Mic Gate dial: adjust it from zero to reduce background noise without cutting out your voice
  • Music slider: volume of music for both the headset and remote listeners. You may also want to adjust the volume in the music player.
  • Zoom slider: volume of remote talkers in Zoom back to your headset

Running Zoom

  1. Test your audio by running through sound calibration again.
  2. Start your Zoom meeting. During the startup, click Test Speaker and Microphone. For the Speaker, choose "VoiceMeeter Aux Input". For the Microphone, choose "VoiceMeeter Output". You should be able to hear sound during both the speaker and microphone test.
  3. Before allowing others to join the class, you may want to do a video and sound test by also joining Zoom from another device to see and hear what the participants will experience.
  4. Click Mute all Participants. This is especially important while playing music. Only unmute when necessary for discussion.
  5. Once another person has joined, right click your video and click Spotlight Video. This important to keep your video the focus for all of the students.

Troubleshooting

  1. Error message when selecting the A1 HARDWARE OUT. Try another prefix option for your headset like MME. Try a reboot.
  2. If the music is garbled, in Voicemeeter, click Menu - System Settings. Try clicking the WDM Input Exclusive Mode once or twice.
  3. For further instructions, see the manual for Voicemeeter Banana: https://www.vb-audio.com/Voicemeeter/VoicemeeterBanana_UserManual.pdf

Finance Clerk Best Practices and Tips

The following are my personal opinions of serving in the Assistant Ward Clerk - Finance calling. Please follow current Church Guidelines and Priesthood Leaders.

Donations

  1. Learn the hotkeys in MLS:
    • Up and down arrow for finding names
    • Tab or enter for advancing to the next field
    • Page Down and Up for advancing to check section and cash/coin fields
    • Alt-S to save donation
  2. Some folks like to open the envelopes to check accuracy and create a pile of the donation paperwork before entering into the computer. This may work for checks, but envelopes with coins and cash are just too risky. Open each of those envelopes and process one-at-a-time into the computer.
  3. Occasionally, a member may want to donate into a specific missionary's account, but remain anonymous. To prevent accidental disclosure, instead donate the funds to the ward mission fund, followed by a transfer of the same amount to the specific missionary account. You can add a description in the transfer that this is an anonymous donor. 
  4. Educate missionary families:
    • The Church withdraws mission expenses the first month no matter the start date, but does not withdraw the final month.
    • Because they are tax-deductible, donations are a free will offering and thus non-refundable. Families may not want to pre-pay too far in advance into a missionary account in case they come home early for any reason. In the event there is a surplus, donations can be re-categorized after the fact to tithing with the Bishop's permission.
    • Encourage out-of-unit friends and families that want to donate to use the Church's online donation system. Provide them the unit number so that they can look up their missionary. If they choose to mail a check instead, obtain and input their membership ID so that their donation will automatically appear on their annual statement.
  5. Periodically announce to members a reminder to only include fast offering expenses in the fast offering envelopes. Including tithing in unsealed envelopes increases the liability on the Aaronic Priesthood.
  6. Encourage members to use the online donation system. It is simple to use, creates an immediate receipt, and reduces liability on the clerks and Bishopric. Consider posting instructions underneath the envelope/donation slip box.

Expenses

  1. All expenses require some kind of paper evidence and the Bishop's authorization.  For Distribution orders, print out the statement and a signature line for the Bishop. In the event of a lost receipt, ask the member for a signed note with as many details as possible. The note could also include a signature from an additional witness.
  2. Policy requires expense request paperwork, but does not specify the format. For better organization, consider adding the check number and date to the authorization slip as an easy notification that the check has already been printed for that expense request.
  3. Fast offering expenses:
    • Whenever possible, obtain paper or electronic full statements for fast offering expenses before producing the check. Leverage and momentum for obtaining documentation is considerably reduced after the check is delivered. Also, help the Bishop by identifying any irregularities or excesses in the statements.
    • Fast offering checks should generally be written to the service and material providers, not the members. Rather than mailing the checks on behalf of the members, let them assume the responsibility and accountability for delivering the checks.
    • Record the account numbers for the member's account with the provider in the "Purpose" field, otherwise the check may not be associated with the member when received by the provider. Watch out for a bug in MLS--if you forget to add the account number before saving, do not try to edit the check memo afterwards. It won't save; instead delete the expense and create a new one.

Budget

  1. Push accountability to the organizations by avoiding shared categories, e.g. Curriculum, Distribution Center. Shared budget categories are prone to overspending, because responsibility is spread too thin. Instead, require the auxiliaries to budget manuals and anything that would need to be ordered from the Distribution Center or Staples. When a Distribution Center order expense posts in MLS, go into the expense, recategorize to the requesting auxiliary, and type a description that the "____ expense is charged to the specific _____ organization."
  2. During the annual budget planning, ask budget owners (typically Ward Council) to submit a budget request with line items. 
  3. Consolidate the budget requests into a single spreadsheet workbook. Meet with the Bishop to consider each line item, and allocate the request amount, less or more. This may consistitute a pre-approval for the expense, as required by the handbook.
  4. When allocating the annual budget, hold back a "Management reserve" of 5 to 15% to allow the Bishop to consider unexpected new budget requests throughout the year.
  5. Remind leaders and members to always reimburse items and services for their calling. They may be acting with an attitude of service, but it is not fair to other members of less financial resources, and it against policy. Watch out for gas on long distance trips and nursery snacks. 

Records

  1. A Finance Clerk strives to reduce the administrative burden of the Bishop, who maintains the ultimate responsibility for Finances. Rather than tracking the Bishop down for every signature, place all the paperwork in a secure folder so that he may sign at his convenience in his week and return back to the Finance box.
  2. Store all records in a consistent order. Newest in front works well.
  3. Batch reports are not audited, and may be a waste of paper to print. Perhaps the Finance Clerk may ask others who are conducing financial transacations in his absence to print this out and place in his box so he can review transactions upon his return.

Tithing Settlement


  1. Use Tithing Settlement to update Individual Ordinance Summary sheets, take pictures, conduct surveys, creating LDS.org accounts, and educating on using the online tools.
  2. With the Bishop's approval, you may need to knock on the door to help keep the schedule with everyone the Bishop needs to visit with. The Bishop may choose to continue or schedule a follow-up appointment to speak with the family further.

Tax Statements


  1. Tax statements are typically made available during the week before the last Sunday of January.
  2. Starting with the 2015 tax year, use the Church's new consolidated statements that track donations across multiple wards. They come pre-signed by the Treasury department and don't require burdening the Bishop with signatures.
  3. Encourage members to obtain their tax statements on lds.org. Educate them that there is an option to consolidate the spouses donation on their statement, but the spouse will need to login and click the option.
  4. Consolidated pre-signed statements for members that have never used the online system will appear in MLS under Finance Statements. Depending on the circumstance, this may be a good opportunity to educate the members how to use the Church's online resources.
