Advanced Settings

The Advanced Settings page collects fine-grained controls intended for power users. Settings are organized into a tree of categories you can expand or collapse on the left of the dialog. Some settings — language, audio backend choice — only take effect after restarting the program.

A few categories are conditional. The Statistics Panel category appears only in VoceVista Video Pro. The Audio Backend row appears only on macOS, and the Enable DirectSound input, Enable Loopback recording, Enable ASIO driver, and Graphics Performance entries appear only on Windows.

System

Reopen last session at startup

When checked, VoceVista remembers the files that were open at shutdown and reopens them on the next launch.

Number of uncompressed files to cache

When loading a compressed file (Mp3, Ogg, …), VoceVista first decompresses it into a temporary uncompressed file for fast scrolling and editing. This setting limits how many decompressed files are kept in the temp folder. Reopening a file that is still cached skips decompression entirely, which is much faster.

Cache Folder

A drop-down with two commands. The label also shows the current size of the cache folder in parentheses (or empty if nothing is cached).

Clear Cache Folder

Empty the decompressed-file cache. Useful if disk space is tight.

Show in Explorer / Show in Finder

Open the cache folder in the OS file manager.

Logging Level

The amount of detail written to the log file: None, Errors, Warnings, Messages, Events, or Debug (most verbose). Raise it when troubleshooting; lower it again to keep the log file small.

Language

Set the UI language. Changing the language requires an application restart for every string to update.

Encoders

Default File Type

The file format that File  New uses, and the default format suggested in save dialogs.

MP3 Compression Quality

The MP3 LAME-encoder preset used when exporting MP3 files:

Insane (320 kbps)

Highest quality, largest files.

Extreme (200–240 kbps)

Near-transparent quality.

Standard (170–210 kbps)

Default. Good quality / size balance.

Medium (150–180 kbps)

Smaller files, audible compression artefacts on demanding material.

Display

Show Timeline on top

Show the timeline above the spectrogram instead of below it.

Waveform

Waveform uses Decibel

When checked, the waveform and timeline use a logarithmic (dB) intensity scale instead of a linear one.

Use symmetric waveform

When checked, the waveform and timeline draw intensity symmetrically above and below the zero line. Unchecked draws the actual signed sample values.

Scales

Use vertical scale labels

When checked, scale labels along the Y axis are drawn vertically. Vertical labels save horizontal space; horizontal labels are easier to read. The setting is also accessible by right-clicking the actual scale.

scaleTextHorzEN

scaleTextVertEN

Y-Scale with horizontal text

Scale with vertical text

Show only scale units

By default the scales include the name and unit (e.g. "Time (s)", "Frequency (Hz)"). When checked, only the unit is shown ("s", "Hz").

Show all secondary time scales

Show the time scale on every secondary view (Waveform, EGG, Vibrato), not only the main spectrogram.

Show Timeline Amplitude Scale

Show the amplitude axis on the Timeline view.

Markers

These visibility toggles refine which markers are drawn where, on top of the per-marker-type visibility set in the Markers menu.

Draw marker heads on timeline

When checked, marker labels appear on the timeline. When unchecked, only the marker boundaries are drawn there.

Show markers above spectrogram

When checked, markers are drawn above the spectrogram (subject to the per-type visibility settings in the Markers menu).

Initial Time Range (in seconds)

The time range used for new empty documents. Default: 10 seconds.

Fixed Timeline Range (in minutes)

By default, the timeline range starts at 10 seconds and grows as the recording grows. Setting a value here pins the timeline to that length at all times.

Initial number of note sliders

The number of Note Sliders used for new empty documents and for existing documents loaded for the first time.

Spectrogram Scroll Mode

What the spectrogram does when the time cursor reaches the end of the visible range during recording or playback.

Scrolling

Keep the time cursor at a fixed position and slide the spectrogram to the left.

Paging

Switch to a fresh empty page and let the time cursor advance across it.

Show Spectrogram Orientation Buttons

Show the small icons that switch the spectrogram between vertical and horizontal frequency axes (the same toggle is on the Acoustic Analyzer View page).

Decibel distance for background lines on spectrum

Draws horizontal background lines on the spectrum at this dB interval. The default of 10 dB is a useful coarse grid.

Decibel range of normalized spectrum

The dynamic range shown on the spectrum when Normalize Spectrum is enabled (see Acoustic Analyzer View).

Toolbars are floatable

When checked, toolbars can be undocked and floated as separate windows. When unchecked, they are pinned to their docking positions.

Toolbar Icon Size

The size of toolbar icons: Extra Small, Small, Normal, Large, or Extra Large. Useful on high-DPI displays where the default size feels too small.

Show context menu titles

Show category headers inside right-click context menus, which clarifies what each section is for at the cost of menu height.

Statistics Panel

Available in VoceVista Video Pro

These settings only have an effect in VoceVista Video Pro, which is the edition that ships the Statistics Pane.

Statistics Panel updates/second

How often the Statistics Pane recomputes its measurements during playback or recording. Lower this on slow computers.

Show full spectrum time range

When checked, the Statistics Pane computes its values across the full spectrum-analysis time window rather than just the cursor instant.

Recording

Insert silence after each take (in seconds)

The number of seconds of silence appended to the file each time recording is stopped. Useful for keeping takes visually separated on the timeline.

Automatically start recording when program starts

When checked, the program starts recording into a new empty file at launch. The same effect can be triggered by passing /record on the command line.

Clear recording after this many seconds

Allows the program to run continuously without filling the disk: when the recording reaches this length, it is discarded and a new recording starts. Useful for long unattended monitoring sessions.

Close unsaved files without confirmation

When checked, closing an unsaved file does not prompt for confirmation. Saves time when working with throwaway recordings; risky when working with takes you care about.

When checked, opening the Open Web Link dialog automatically pastes a URL from the clipboard if one is found. Saves a click when you copy a link before opening the dialog.

File Export

Show exported files in Explorer / Finder

When checked, the OS file manager opens to show the exported file after each export. Unchecked keeps focus on VoceVista.

Signal Generator

The Signal Generator plays a test signal over a sound output, used mainly to measure the resonance of the oral cavity by playing a known signal into it and analyzing the echo.

Play signal while recording

When checked, the test signal plays continuously during recording.

Wave Output Device

The output device used for the test signal. Pick a separate device from your main playback device when you want the test signal in one place (e.g. a small speaker pointed at the singer) and the recording playback elsewhere.

Frequency (Hz)

The frequency of the test signal in Hertz. The current implementation plays a square wave at maximum amplitude.

Signal Phase Ratio

The ratio of the up phase to the total period of the square wave. 0.5 produces a symmetric signal; smaller values produce a short up spike followed by a longer down period — useful for varying the harmonic content of the test tone.

Cursor Lines

Show Playback Cursor Line

Show the green vertical line that indicates the current playback position. Turning it off is mostly useful when taking screenshots.

The visibility of the time, frequency, intensity, and time-range cursor lines moved to the Selection and Pointer page in a recent release. Set them there.

Vowel Chart

These settings control the appearance and behaviour of the Vowel Chart.

Show Vowel Chart Toolbar

Show the small toolbar at the top of the Vowel Chart with quick toggles for the most common chart options.

Show Harmonic Matrix

Overlay a grid of harmonics on the vowel chart for reference.

Show Harmonic Vowels

Annotate the chart with the vowel positions corresponding to each harmonic.

Show note names for f1/f2

Annotate the chart axes with note names for the first two vocal-tract resonances (fR1 and fR2).

Scale Mode

Whether the fR1 / fR2 axes use a linear or logarithmic scale.

Lock aspect ratio

When checked, the fR1 / fR2 axes are forced to the same scale, which keeps vowel-chart shapes recognizable when the window is resized.

Play Vowels

When checked, hovering over a vowel position in the chart synthesizes the corresponding sound through the Wave Output Device.

fR1 / fR2 Min and Max (Hz)

Four separate fields — fR1 Min (Hz), fR1 Max (Hz), fR2 Min (Hz), fR2 Max (Hz) — set the lower and upper bounds of the two resonance axes on the vowel chart.

Audio Performance

Audio Backend (macOS only)

Choose which low-level audio API VoceVista uses for capture and playback. The default is the cross-platform PortAudio backend; RtAudio and Qt Audio are available as fallback options when a device misbehaves under PortAudio. Changing the backend takes effect after restarting the program.

Enable DirectSound input (Windows only)

When checked, the DirectSound API is available for input. DirectSound performs automatic sample-rate conversion in software, which is convenient when the device’s hardware rate doesn’t match the recording rate.

Enable Loopback recording (Windows only)

When checked (and WASAPI support is available), you can record "what you hear" by selecting your output device as the input source. Disabling Loopback hides such devices from the input list.

Enable ASIO driver (Windows only)

When checked, the ASIO API is available for low-latency input and output. The same toggle exists on the Recording Settings page.

Recording Latency (ms)

The approximate time between a sound arriving at the microphone and its appearance on the screen. Lower values mean the analyzer feels more responsive; values that are too low can cause clicks or gaps in the recording when the computer cannot keep up.

File Playback Latency (ms)

Same as the recording latency, but for playback. Lower values reduce the lag between actions (changing playback position, toggling a filter) and the audible response. Values that are too low can cause audible clicks during playback.

Fade-In/Out Duration (ms)

The fade-in / fade-out time applied at the boundary of selections and takes during playback. A small fade prevents clicks at edit points; too much fade audibly softens the transitions.

Disable sleep for recording and playback

When checked, the operating system is prevented from sleeping while VoceVista is recording or playing. Long unattended recordings won’t be cut short by power-management policies.

Frequency Filters

Filter Size

The FFT size used by the frequency-filter engine. Larger sizes give sharper filter cut-offs at the cost of higher latency. The values are powers of two from 1024 up to 65536.

Tone Generator

These settings affect only the Sine Wave Generator that plays overtones and piano keys.

Sampling Rate

The sampling rate at which the tone generator synthesizes samples.

Playback Latency (ms)

The latency of the tone generator’s output. A lower value makes the program feel more responsive when you slide a slider’s pitch in real time.

Input Level Meter

The Input Level Meter is the slider on the toolbar that shows input volume and the current input signal strength.

Enable monitoring

When the Input Level Meter is enabled, VoceVista continuously records from the input device so the meter can move. Turn this off to suspend that recording.

The same toggle is on the right-click context menu of the level meter on the toolbar.

Displayed range (in dB)

The dynamic range displayed on the meter.

Max. updates per second

How often the Input Level Meter is redrawn. Lower this if the meter takes too much CPU on a slow computer.

Peak History (seconds)

The duration over which the peak indicator is held. With a 3-second peak history, the meter shows the maximum value seen in the last 3 seconds before decaying.

Graphics Performance (Windows only)

MSAA Samples

The number of multisample-antialiasing samples used when rendering the spectrogram and other visualizations. Higher values smooth edges at the cost of GPU work.
