Question 1

What is Audify and how does it process audio?

Accepted Answer

Audify is an in-browser audio workstation and preset laboratory designed for fast, high-fidelity sound manipulation. Unlike cloud converters that upload your audio to third-party servers, Audify processes everything directly on your device using the HTML5 Web Audio API and WebAssembly.

Question 2

Do I need to install any software or create an account?

Accepted Answer

No. Audify requires no downloads, plugins, or account registration. It runs instantly in all modern desktop and mobile browsers, including Chrome, Safari, Firefox, and Edge. Your settings and audio buffers exist only in your current browser session.

Question 3

Can I use Audify on a smartphone or tablet?

Accepted Answer

Yes. Audify is fully responsive and touch-friendly on iOS and Android. Because mobile browsers enforce strict memory ceilings on individual browser tabs, we maintain a 10 MB file limit to prevent tab crashes and keep playback smooth.

Question 4

Does processing in the browser degrade audio quality?

Accepted Answer

No. When you import audio, Audify decodes it into 32-bit floating-point linear PCM buffers. All digital signal processing—including biquad filters, convolution reverb, and stereo spatialization—operates with full 32-bit float headroom (+770 dB before digital clipping). Audio is only compressed or quantized if you choose a lossy export format like MP3.

Question 5

What is the difference between Varispeed and independent pitch shifting?

Accepted Answer

In standard Varispeed mode (used by Slowed + Reverb or Nightcore), playback rate and pitch are physically linked—slowing playback drops pitch, while speeding up raises pitch, exactly like analog tape or vinyl. When pitch must change independently from tempo, Audify employs polyphase sinc resampling to shift semitones while preserving timeline duration.

Question 6

Why does Audify compute audio locally instead of in the cloud?

Accepted Answer

Local DSP provides zero upload delay, instantaneous waveform scrub feedback, absolute confidentiality, and offline capability. Your audio never queues on a server or consumes bandwidth.

Question 7

How do Audify presets work under the hood?

Accepted Answer

Presets are modular DSP routing chains assembled from real Web Audio nodes: multi-pole IIR biquad filters, synthetic convolution reverb impulse responses, LFO-modulated stereo panners, and waveshaper saturators.

Question 8

Can I customize preset parameters after applying them?

Accepted Answer

Yes. Every preset provides full parameter transparency. In Studio, you can adjust playback speed, pitch semitones, reverb wet/dry blend, decay time, three-band EQ bands (low, mid, high), and stereo widening.

Question 9

Why are headphones required for 8D Audio and spatial presets?

Accepted Answer

8D Audio and binaural spatial presets rely on dynamic interaural time difference (ITD) and interaural level difference (ILD) stereo panning between your left and right ears. Standard laptop or phone speakers mix sound waves in the open air (acoustic crosstalk), eliminating the 360-degree rotational illusion. Stereo headphones or in-ear monitors are required.

Question 10

What audio processing utilities does Audify include beyond creative presets?

Accepted Answer

Audify includes a full suite of professional engineering utilities: Dynamic Compressor with parallel wet/dry blending, Audio Trimmer & Cutter, Multi-Format Audio Converter (WAV, MP3, AIFF), Vocal Remover with Mid/Side center extraction, Stereo to Mono Downmixer, DC Offset Remover, 3-Band Parametric Equalizer, Sub Rumble Cut, Noise Gate, Fade In/Out, Bitcrusher, and BPM Detector.

Question 11

What is the difference between dynamic compression and peak normalization?

Accepted Answer

Peak normalization applies a single fixed mathematical multiplier across your entire track so the single loudest transient sample reaches a target ceiling (e.g., -0.3 dBFS). It does not alter the relative dynamic range between quiet and loud passages. Dynamic compression, by contrast, dynamically attenuates loud peaks that exceed a threshold based on a configured ratio, attack time, and release time, narrowing the overall dynamic range and allowing makeup gain to increase perceived punch and presence.

Question 12

How does the Audio Trimmer and Cutter work?

Accepted Answer

The Audio Trimmer allows you to set precise start and end time boundaries with millisecond accuracy. Because slicing operates directly on the decoded 32-bit float PCM sample arrays in memory, trimming is instantaneous and completely free of generational transcoding quality loss.

Question 13

How does Audify convert audio formats without a server?

Accepted Answer

When you choose format conversion, Audify decodes the input container into raw 32-bit floating point audio in browser memory, processes any active DSP filters or gain stages, and directly synthesizes valid bitstreams using Web Audio PCM encoders (for 16-bit, 24-bit, or 32-bit float WAV and big-endian AIFF) or our client-side WebAssembly LAME engine for MP3 at up to 320 kbps CBR.

Question 14

How does the Vocal Remover and Center Extractor work?

Accepted Answer

In modern commercial stereo recordings, lead vocals are typically mixed dead-center with equal amplitude and phase in both left and right channels, whereas instruments like guitars, synthesizers, and reverbs are panned wide. The Vocal Remover creates an acoustic difference signal (L - R) that cancels out the center-panned vocal frequencies. A low-frequency crossover filter preserves the sub-bass and kick drum below your selected cutoff frequency so low-end punch is not lost.

Question 15

What is DC offset and why should I remove it?

Accepted Answer

DC offset is an asymmetrical electrical bias introduced by flawed audio interfaces, budget microphones, or analog circuitry that causes the entire audio waveform to drift above or below the 0.0 V center line. This offset robs valuable dynamic headroom, causes low-frequency 'thump' clicks during edits, and reduces maximum loudness. Audify's DC Offset Remover measures the channel mean displacement and subtracts the bias, recentering the waveform on 0.0 V.

Question 16

Which audio formats and containers can I import?

Accepted Answer

Audify supports standard browser-decodable audio containers and codecs: MP3, WAV, OGG (Vorbis and Opus), FLAC, and AAC / M4A. Audio files must have valid container headers and stay within our 10 MB and 10-minute duration ceiling.

Question 17

What export formats and quality profiles are available?

Accepted Answer

You can export uncompressed 16-bit, 24-bit, or 32-bit float WAV (at 44.1 kHz or 48.0 kHz) for lossless preservation, or encode to MP3 using our client-side LAME encoder at selectable bitrates up to 320 kbps CBR.

Question 18

How does the export limiter prevent clipping and distortion?

Accepted Answer

Every rendered master output passes through a look-ahead true-peak limiter calibrated to −0.3 dBFS. This ceiling provides inter-sample headroom, preventing digital overs and harsh clipping distortion even when heavy low-shelf EQ boosts or resonant filters add substantial gain.

Question 19

Do my audio files or waveforms ever leave my computer?

Accepted Answer

Never. Audify adheres to a zero-telemetry architecture. All decoding, waveform rendering, DSP calculation, and export encoding occur in volatile browser memory on your device. No audio chunks or files are ever uploaded or transmitted across the network.

Question 20

Why is there a 10 MB and 10-minute file size limit?

Accepted Answer

Because browser-based audio requires decoding compressed audio into raw 32-bit float PCM buffers (where 5 minutes of stereo audio consumes ~50 MB of raw memory, and multi-pass convolution impulse processing requires working buffers), the 10 MB ceiling guarantees stable performance across all consumer laptops and smartphones without tab memory exhaustion.

Question 21

What happens to my audio data when I close or refresh the tab?

Accepted Answer

Audio buffers exist strictly in temporary browser heap memory. As soon as you navigate away, reload, or close the browser tab, the browser runtime immediately garbage-collects all audio buffers. No audio is cached to disk, LocalStorage, or cookies.

Question 22

Why did my audio file fail to import or decode?

Accepted Answer

Common reasons include DRM protection (such as Apple Music .m4p or protected streaming downloads), corrupt file headers, unsupported proprietary codecs, or files exceeding the 10 MB limit. Try re-encoding your source file to standard 16-bit 44.1 kHz WAV or standard MP3 using an audio utility, then import it again.

Question 23

Why is playback stuttering or dropping audio samples?

Accepted Answer

Complex preset graphs (e.g., high-order biquad filters combined with long convolution reverbs and active spatial panning) can saturate single-core CPU threads in older devices. Close background tabs consuming CPU resources, or render the file directly via the Export panel—offline export renders mathematically at full precision without stutter.

Question 24

Why does audio pause when my mobile screen turns off?

Accepted Answer

Mobile operating systems (iOS Safari and Android Chrome) intentionally suspend Web Audio clock timers when the screen locks or when switching to background apps to save battery power. Keep your browser active and your screen awake while listening to previews or rendering exports.
