allow user to change "originalVolume"-Setting in ui per lang-channel

current state

• key settings of the intrpretation feature can only be set server-wide (html5-config-yml)
• it is not possible to adapt to different audio-levels of different participants / translators

goal

• make some settings available to the user in the html5-ui
• yml-settings could be default, user could change them in an active session without affecting server or other clients

settings:

• origineVolume - for users, per language channel (how much is the original volume attenuated when an interpreter is speaking

how to do it in ui?

• in the left sidebar add a slider above the user list (for participants' point of view)
  • section title "Interpretation Volume"
  • when user has chosen an interpretation channel to listen to, always only one slider visible, when user has chosen "floor" to listen to, show no slider and hide the whole section
  • left end of the slider has the label "original"
  • right end of the slider has the label "interpretation
• the slider position determines the mixing ratio between original and interpreted audio
  • leftmost position: original at 100%, interpretation at 0%
  • rightmost position: original at 0%, interpretation at 100%
  • center: original at 100%, interpretation at 100%
  • values for originalvolume and interpretationvolume is computed from the sliderposition and are updated while moving the slider
• the slider has a linear scale
  • is this the right choice? we will see
  • (alternative would be a logarithmic scale so that there is more resolution for the user towards the corners and less resolution towards the center)
• initialize the slider value from the config value originalVolume
  • e.g. for the value 0.3 the slider should be initially at a position almost all the way to the right
• keep the value (sliderposition) per language while session is running
• on switching the language initialize the slider with the value for the new language (or hide it completely)

changed the description

changed title from WIP change transation settings on client-side to WIP change translation settings on client-side

changed the description

• in the language menu whe user chooses the lan to listen to, add a slider (originalvolume) on the row of the active language
• keep value per language while session is running
• show slider only for active language

• threshold setting could be in the sidebar "languages"
• maybe local feedback in ui neccesary for this to be usable

test:

• slider in left sidebar under "translation" visible for everyone when translation is active
• use originevolume value
• maybe logarithmic scale
• ui text "interpretation only" left, "both" right

@jens.moeller I have just deployed a test version with this feature on bbb80.wechange.de, so you can give it a try.

changed the description

@martin.klampfer at the test-event from a week ago, we came up with an updated concept. see description. What do you think of this?

mentioned in issue #111 (closed)

assigned to @jens.moeller

we tested this on https://git.fairkom.net/chat/fairblue/-/tags/release_211015

• the volume slider had no effect at all
  • chrome Version 94.0.4606.71 (Official Build) for Linux Mint (64-bit) or ff linux 93.0 (64-bit)
• after interpreter reconnected in this test,
  • the slider worked while interpreter was audible in floor and interpreteationchannel at the same time
    • max left: interpreter audible with "echo" effect of both channels active
    • max ritht: interpreter audible without "echo"
  • this means, the slider did not work as described in this ticket
    • leftmost position: original at 100%, interpretation at 0%
    • rightmost position: original at 0%, interpretation at 100%

test sequence

2 persons

• setup
  • listener switches to channel 1
  • interpreter speaks to channel 1
• volume slider appears for the listener
• listener moves the volume slider -> volume of interpreter changes
  • max right the interpreter has max volume
  • max left the interpreter is not audible at all

unassigned @jens.moeller

added Important label

Same happened on our side. The slider is really a nice feature - but being able to switch to 100% interpretation (standard case) is even more important for us. Especially if people cannot reduce the volume from 50/50 to something more acceptable, they consider it not working and we get only complains. We have cases when this happens and the slider does not work.

yes according to the ticket description it should be possible to go from only original via both to only interpretation but we never saw this working..

I have just deployed a version to dev with the sliders working as you suggested (mixed evenly when at center position). Reconnecting once is still required but I'll soon have sorted that out as well.

@martin.klampfer can you explain this in more detail? I think i am missing something..

You wrote in the comment above a week ago that the volume slider had no effect at first, but did have an effect after the interpreter had reconnected. This reconnect (basically hitting F5 once) was still necessary when I tested it, but after the reconnect, it is now working according to the description (left: 100% floor, center: 50-50, right: 100% interpreter).

TEST on 2021-11-11 on dev.fairteaching

• slider it worked fine and from the start without reconnect on FF and Chrome

UI bug slider partly covered

• in FF when the left sidebar is narrow, the slider-handle is covered on the right border
• this was the initial state for one of our testers
• i was able to reproduce this, by adjusting the width via the mouse

Release is here: https://git.fairkom.net/chat/fairblue/-/tags/release_211114

diskussion with martin, jens:

• currently https://git.fairkom.net/chat/fairblue/-/tags/release_211114

  • attenuation while interpreter speaks is currently disabled
  • while interpreter is not speaking, and slider is at max interptetation, user does not hear original audio

• possible solution -> future enhancement

  • config switch speechdetection enabled:
    • while interpreter is speaking: slider is active
    • while interpreter is not speaking: original is at 100% volume
