Of course, I will share everything needed here, even the effects I
applied to the live stream in case they are useful in finding what's
wrong.
binaural = input.pulseaudio(device =
"alsa_input.usb-ZOOM_Corporation_F3-00.analog-stereo")
live =
input.harbor("harbor",port=8005,user="username",password="password",icy=true)
def multiband_band(live, from, _to, attack, release, ratio, threshold, gain)
high_live = filter.iir.eq.high(live, frequency = from,)
live_filtered = filter.iir.eq.low(high_live, frequency = _to,)
live_compressed = ladspa.tap_limiter(limit_level = -0.5,
ladspa.sc4(rms_peak = 0.5, attack_time = attack, release_time = release,
threshold_level = threshold, ratio=ratio, makeup_gain = gain, live_filtered))
live_compressed
end
live = ladspa.gate(live, threshold = -80.0, attack = 0.15, hold = 1.0, decay =
200.0, range = -25.0)
live = normalize(gain_min = -16., gain_max = 0., target = 0.5, live)
live = ladspa.sc4(rms_peak=0.3, attack_time = 0.5, release_time = 3.,
threshold_level = -36.0, ratio=1., makeup_gain = 6., live)
live = ladspa.tap_equalizer(band_1_freq=70., band_1_gain=4., live)
live = ladspa.tap_equalizer(band_1_freq=150., band_1_gain=-2., live)
live = add(normalize=false,
[
multiband_band(live, 0., 200., 3.5, 30., 3., -10., 2.),
multiband_band(live, 200., 1000., 2.25, 40., 2., -13., 2.),
multiband_band(live, 1000., 3500., 2.25, 40., 3., -9., 2.),
multiband_band(live, 3500., 6500., 2.25, 60., 2., -6., 1.5),
multiband_band(live, 6500., 20000., 2.25, 70., 2., -4., 1.)
])
live = ladspa.tap_limiter(limit_level = -0.5, live)
# Set to `true` when we should be adding
# silence
should_append = ref(false)
# Append 10. of silence when needed.
silence_source = append(
binaural, fun (_) ->
if should_append() then
should_append := false
blank(duration=10.)
else
source.fail()
end
)
# Transition to live
def to_live(binaural, live) =
sequence([binaural,live])
end
# Transition back to playlist
def to_binaural(live, binaural) =
# Ask to insert a silent track.
should_append := true
# Cancel current track. This will also set the playlist
# to play a new track. If needed, `cancel_pending` can
# be used to for a new silent track without skipping the
# playlist current track.
silence_source.skip()
sequence([live, binaural])
end
source = fallback(
track_sensitive=false,
transitions=[to_live, to_binaural],
[live, silence_source]
)
I stream to icecast in mp3.cbr with a 192 kbps bitrate, in case this matters.
I also see the blanks coming on and going, and the append track being played,
except it doesn't play any silence and just goes back to pulseaudio.
Hope this helps!
