Auphonic

Auphonic suits podcasters, broadcasters and other spoken-word producers who need more than basic noise cleanup, especially when processing recurring or multitrack work. Its broad mix of audio, transcription and workflow tools is a strong fit for production pipelines, but free users give up several useful features and must work around short retention windows.

Overview

Auphonic is a batch-processing service for polishing audio and video productions, from interviews and lectures to podcasts and audiobooks. It combines sound treatment, mixing, speech tools and delivery integrations rather than focusing on a single cleanup task. That breadth helps when several production steps need to fit into one workflow; it is less compelling for someone who only wants a quick fix to one recording.

Founded in 2013 and headquartered in Graz, Austria, Auphonic stores data primarily on servers in Germany. Productions and related media are permanently deleted after 21 days for audio and API productions, and after 7 days for video productions. EU users' media remains in EU jurisdiction. Auphonic says it complies with the EU General Data Protection Regulation worldwide; paying customers can request a Data Processing Agreement. The retention window is worth factoring into workflows that need longer-term access to source or output files.

Key features

Audio processing and multitrack

Auphonic can reduce noise and reverb, level and filter recordings, enhance audio, and target loudness specifications. It can also cut filler words, coughs and silence automatically. Those tools can reduce routine cleanup, although automatic cutting is best treated as an editing aid rather than a substitute for decisions about what should remain in a recording.

For multitrack productions, it builds optimized mixdowns using automatic ducking, noise gates and mic-bleed removal. That makes it more useful for recordings made with several microphones than a single-track denoiser. Billing is based on processed audio duration, with a minimum charge of 3 minutes per production, so very short jobs may count as more than their actual length.

Speech, video and delivery

Multilingual speech recognition supports transcripts, automatic shownotes and chapters, with a shareable transcript editor. Auphonic uses a self-hosted multilingual Whisper model as well as external recognition services. It also supports common audio and video formats, waveform audiograms, metadata and chapters, plus burned-in styled subtitles. Together, those features suit producers who want to handle more of a spoken-word release in one place; the free tier excludes multilingual recognition, shownotes and chapters.

Integrations include FTP and SFTP, Dropbox, Google Drive, OneDrive, Amazon S3, YouTube, Libsyn, Spreaker, SoundCloud, PodBean, Zapier, n8n and several speech-recognition providers. A developer API, CLI, watch folders and batch productions support automated workflows. The free CLI has static binaries for Linux, macOS and Windows.

Pricing

Auphonic is freemium, with a free plan and a free trial. The free plan costs nothing and includes 2 h/month, AI-based audio algorithms and a jingle in free productions; credits do not stack. Free accounts can process multitrack productions under 20 minutes, but do not get multilingual speech recognition, automatic shownotes and chapters, watch folders or batch productions. That makes the free option useful for limited experiments or short multitrack work, not a full test of the paid workflow features.

Paid subscriptions scale by monthly audio allowance. Auphonic S costs $11 a year (billed monthly equivalent when billed yearly) for 9 h/month; M costs $25 a year (billed monthly equivalent when billed yearly) for 21 h/month; L costs $52 a year (billed monthly equivalent when billed yearly) for 45 h/month; and XL costs $113 a year (billed monthly equivalent when billed yearly) for 100 h/month. Yearly billing saves 20%. These tiers suit producers who can estimate a steady workload and do not need the largest quota.

Auphonic XXL costs $290 a month (billed monthly) for 250 h/month. Credits reset monthly and unused credits do not roll over, so this tier fits heavier, predictable volume better than uneven workloads. Free plans include basic support; monthly and one-time plans include standard support, while yearly and business plans include priority support.

Platforms

Auphonic is available on the web and through an API, with platform support for Linux, macOS and Windows. Its CLI is free and provides static binaries for all three desktop operating systems.

Who it's for

Auphonic is a strong choice for podcasters, radio and broadcast producers, educators, interviewers and audiobook creators who need consistent audio processing, multitrack mixing or repeatable delivery. It is particularly appealing when transcription, chapters, subtitles or automation are part of the same production process. Someone seeking only desktop voice isolation or a single quick denoise pass may prefer a more focused tool.

Pros and cons

• Pros: Noise and reverb reduction, leveling, loudness targeting and automatic cuts cover several common cleanup jobs.
• Pros: Multitrack mixdowns add ducking, noise gates and mic-bleed removal for more complex recordings.
• Pros: Transcription, shownotes, chapters, subtitles and broad service integrations can connect processing with publishing workflows.
• Cons: Free accounts lack multilingual recognition, shownotes, chapters, watch folders and batch productions, limiting their usefulness for a complete workflow.
• Cons: Audio and API productions are deleted after 21 days, and video productions after 7 days, so users must manage their own longer-term copies.
• Cons: The 3-minute minimum per production can make very short jobs count for more processed duration than their runtime.

Alternatives

LALAL.AI is another freemium option with broad platform support; its free Starter plan limits users to 10 minutes in a relaxed queue, a 200 MB upload limit per file and previews without full downloads. Choose Riverside Magic Audio if its free offer of 2 hours of multitrack recordings, up to 720p video and 44.1 kHz audio suits your needs, bearing in mind that free output carries a Riverside watermark. CrystalSound is an alternative with Linux, macOS and Windows support. For mobile denoising, Denoise runs on Android and iOS; its free tier lets users import and denoise and hear the full before-and-after, but saving or exporting requires Pro. AudioEnhancerMAX is a free alternative available on Android, Linux, macOS, web and Windows. DeepFilterNet is a free, open-source option for Linux, macOS and Windows. Adobe Enhance Speech is web-based and free for audio-only, one-file-at-a-time enhancement, with a 30-minute and 500 MB per-file maximum and a daily hour limit. NoiseTorch-ng is a free Linux option for PulseAudio or PipeWire users.

Verdict

Choose Auphonic if you produce spoken-word audio regularly and want cleanup, multitrack processing, speech tools and automation in one service. Its strongest case is the range of production tasks it brings together; its main drawbacks are the free tier's feature exclusions, short media retention and billing minimum. For an occasional single-track cleanup, a narrower denoising tool may be a better fit.
