About SoundSpice

SoundSpice takes a recording that sounds bad and hands it back clean. You drop in a file and processing starts at once — there is no setup screen, no rack of faders and no decision to make before you can already hear the improvement. The app measures your sound, repairs what is actually wrong with it, levels it to a loudness target, and then shows you, in real units, exactly what it changed.

The repair pass is driven by measurement rather than presets, and each stage only fires where your recording needs it. Mains hum at 50 or 60 Hz is notched out along with its harmonics. Background noise, hiss and room tone are reduced against a noise profile taken from your own file. Clipped peaks are reconstructed, rumble and DC offset are removed, and a lopsided stereo image is brought back to centre. Harsh sibilance is tamed on speech, muddy, boxy or thin tonal balance is corrected by wide and gentle automatic EQ, uneven levels are steadied, flat over-compressed audio is given its transients back, and the whole file is normalized with true peaks held at −1 dBTP. Nothing about this is aggressive: every stage has guardrails, does less when in doubt, and never touches your original file. SoundSpice is built to avoid making a recording worse, not to promise that any recording can be rescued.

Once the repair pass is done you can add character, or leave it alone. Eight finishing blends sit behind a single tap — None keeps the processed file with nothing added, Natural adds gentle warmth below 100 Hz and smooths above 8 kHz, Voice lifts speech presence around 3 kHz and steadies the level, Warmth rounds the lows and softens the upper mids, Brightness opens the top above 10 kHz with a touch of width, Punch sharpens transients and firms up the low end, Depth adds weight that carries on small speakers, and Vintage brings tape-style saturation with a softened top. Each blend comes in Light, Medium and Strong, and switching between them is instant because the expensive corrective pass is computed only once.

What makes SoundSpice unusual is that it shows its work. The result screen is two plotted figures with real axes: a spectrum comparison of the original against the processed file on a log frequency axis, with the regions the chain acted on shaded, and seven band levels across the whole file on one shared dB scale with a live playhead. Beside them sit before-and-after numbers — integrated loudness in LUFS, true peak in dBTP, loudness range in LU and the noise floor in dBFS — and a plain-language summary of what was found and then applied, taken from the run itself, so a stage that never fired is never claimed. The Original and Processed comparison is loudness-matched by default, which means louder cannot quietly pass for better.

It fits the files you already have and the places they are going. SoundSpice opens WAV, AIFF, CAF, MP3, AAC/M4A, ALAC, FLAC, Ogg Vorbis and Opus, along with the audio track of MP4 and MOV video, at sample rates up to 192 kHz. It exports M4A at 256 kbps AAC, ALAC, WAV, AIFF or FLAC with source metadata intact, aimed at −14 LUFS for streaming, −16 LUFS for podcasts, −23 LUFS for broadcast under EBU R128, or left as-is. You can start from the share sheet with “Enhance with SoundSpice”, from Files, or by dropping a file anywhere in the window; on the Mac you can drag the finished result straight out into Finder or Mail. Processing runs many times faster than real time, and long files finish in the background.

Who is SoundSpice for?

• Podcasters and interviewers cleaning up remote calls and phone recordings before they publish
• Musicians polishing demos, rehearsal captures and phone-recorded ideas without opening a DAW
• Students, journalists and researchers with field recordings, lecture audio and voice memos that need to be listenable
• Video creators fixing noisy camera and on-location audio, straight from the MP4 or MOV
• Privacy-minded people who will not upload an interview, a confidential recording or a rough demo to somebody else’s server
• Anyone with a recording that sounds bad and no wish to learn what a compressor is

Why choose SoundSpice?

Most audio repair tools look like cockpits, and the usual alternative — a web service that does it for you — asks you to hand over the file first. SoundSpice takes the third path: the automation of a one-click cleaner, but running entirely on your iPhone, iPad or Mac. Every measurement and every correction happens locally. The app contains no networking code at all: no server, no cloud, no upload, no account and no analytics, and its App Store privacy label reads “Data Not Collected” as a consequence of how it is built rather than as a promise.

It is also honest about what it did. Because the repair chain is measurement-driven, the numbers and charts on the result screen come from the actual run, not from a template — you can see the hum that was found, the noise floor before and after, the loudness you asked for and the loudness you got. The comparison is loudness-matched so the improvement has to be real, the corrective stages hold back when the evidence is thin, and your original file is left exactly as it was on disk. If a recording is beyond help, you will be able to tell from the charts rather than from marketing copy.

Finally, it is a single fair price. Buy SoundSpice once and the whole app is yours: no subscription, no in-app purchases, no unlocks and no export limits or watermarks. Universal purchase covers iPhone, iPad and Mac, and Family Sharing is enabled, so one purchase serves every device and everyone in the household. Drop in a sound, get a better one back.
