Podcasting, voice-over editing and tidying a music library usually need only one or two small operations: strip the silence at the front, even out the volume, export as MP3. Opening a full DAW for that is overkill. These tools decode the waveform with the Web Audio API and edit at sample level, encoding only once at export, so intermediate steps never stack up generation loss.
Not noticeably. Edits are applied to the decoded PCM waveform and encoding happens only once, at export.
Yes. WAV and FLAC can be read and exported, alongside lossy formats such as MP3, AAC and OGG.
It works well on steady background noise such as air conditioning or electrical hum. For sudden noises, trimming the region out is more effective.
