Soundop is a Windows audio editor from Ivosight Software Inc. for recording, repairing, mixing, and processing audio. It combines an Audio File Editor with a Multitrack Editor, reusable processors, and CD projects. Paid access includes perpetual, subscription, and time-limited licenses.
A fully functional trial precedes Demo mode. Demo continues to open and analyze audio, but it inserts periodic silence into audio exports. The trial requires an internet connection.
Files and mixspaces
The Audio File Editor works directly on a recording, with waveform and spectrogram views. A mixspace instead arranges clips that reference source audio files. Soundop can open a clip’s source in the file editor and preview those changes within the mix.
Several clips can reference the same source, so editing that file affects each reference. Create Unique Source gives a clip its own copy before separate editing. ARA extensions provide another route for editing clip sources without changing the original audio.
Recording inputs and alternative takes
Soundop supports ASIO, WASAPI, MME, and DirectSound devices. Channel mapping connects physical device channels to file channels, while WASAPI loopback captures system playback. File recording offers insert and overwrite modes, a start time and duration, or a signal threshold that starts capture.
In a mixspace, each track has an input device and recording switch. Different tracks can record from different devices simultaneously. Punch recording targets a time range, while Loop Record creates multiple takes within a clip. Users can select an active take or unpack takes into tracks and clip lanes.
Repair within a frequency range
The Marquee Tool selects a rectangle in the spectrogram, combining a time span with a frequency range. Editing then targets that region rather than every frequency in the recording. Soundop also offers ordinary cut, paste, delete, gain, fade, and normalization operations.
Noise Reduction starts with a sample that contains only background noise. Soundop captures its profile, then applies reduction to another selection or the whole file. Reduction amount, sensitivity, and preview controls govern the result. Adaptive Noise Reduction instead computes a changing profile during processing. Interpolate replaces a short selection with an estimate from surrounding audio.
Arrange clips and route tracks
The Multitrack Editor places audio clips along a timeline. Clip controls set gain, fades, pitch, and stretch, while overlapping clips can crossfade. Alternative clip lanes hold different arrangements within a track.
Audio tracks can feed a bus, the master track, or an output device. Sends feed additional destinations with separate level and pan controls. Pre-fader and post-fader settings determine whether a send follows the track’s volume control. Side-chain routing supplies a signal to an effect’s side-chain input.
Effect racks and automation
Soundop applies effects to audio files, tracks, and individual clips. Built-in processors cover equalization, compression, limiting, reverb, delay, and modulation; VST and VST3 plug-ins add external effects. The engine compensates for effect latency.
Container effects provide three different signal structures:
- FX Group passes audio through effects in sequence.
- Parallel FX Groups process the same input independently and blend their outputs.
- Mid-Side Splitter separates the center and stereo-side components for independent processing.
Automation envelopes change parameters during playback and mixdown. Users edit envelope points or record control movements through Write, Latch, and Touch modes. Read mode plays those envelopes. Freezing a track or clip caches its processing; changes that invalidate the cache automatically unfreeze it.
Processors across a file collection
A processor holds an ordered sequence of editing actions, parameters, and selections. Users can reorder or disable actions and run the sequence on an active file. Each action can use its own time selection instead of the current selection.
The Batch Processor adds files or folders, selects a processor, and specifies the output format, filename template, and destination. Folder input can include subfolders and file-type filters. Soundop processes files concurrently by default, with sequential processing available for actions that need manual parameter changes. Saving the batch project preserves its file list and settings.
Measurements, tags, and loop points
Analysis panels show levels, loudness, frequency content, phase, and channel correlation. Frequency Analysis can scan a selection or the whole file. The Metadata panel exposes fields for the target format, including ID3, RIFF, and Vorbis information. Soundop saves applicable metadata within the audio or in an SMX sidecar.
Sampler loop markers define reusable audio ranges. Their controls adjust loop positions and counts, while crossfades smooth the loop boundaries. ACID metadata supplies separate loop information for compatible audio workflows.
Audio exports, video, and discs
Mixdown can render all tracks, a time selection, individual tracks, or particular clips. Output formats include WAV, FLAC, MP3, AAC, and AIFF. With synchronization active, attached video follows audio edits. Video export supports MP4, WMV, and MOV.
A CD project holds an ordered track list with adjustable pauses. Users choose the drive and burn speed, then write the audio CD. Optional verification checks the tracks after burning, and the disc tools can erase rewritable CD media.
