+# Speaking MIDI
+
+An interactive demonstration of **fixed-timbre inverse synthesis**: approximate speech or other audio using only Grand Piano MIDI notes. Upload/record audio, or generate a voice from text with Qwen3-TTS, then compare the source, a spectral-peak baseline, and optimized piano playback. Download the actual MIDI and inspect aligned spectrograms and a velocity-colored piano roll.
+
+English and Chinese examples are available instantly through the two example buttons. They contain about eight seconds of speech each and use the full refinement algorithm. New jobs default to a smaller search budget for responsive CPU experimentation. The technique approximates spectral structure; it does not guarantee intelligible words or perform conventional melody transcription.
+
+## Poetry voice examples
+
+Five ready-made Qwen VoiceDesign recordings cover Chinese and English public-domain poetry: Li Bai’s **Quiet Night Thoughts**, Meng Haoran’s **Spring Dawn**, Wang Zhihuan’s **On the Stork Tower**, the opening couplet of Shakespeare’s **Sonnet 18**, and the first stanza of Blake’s **The Tyger**. Select an example to load and listen to its recording, then press **Generate piano MIDI**. Selection switches to audio mode and sets the fitting window to 12 seconds. These are speech inputs; their MIDI is generated on demand. Text, authorship, durations, and generation provenance are available in [the poetry examples](examples/poetry/README.md).
+
+## Two input modes
+
+- **Audio → MIDI:** upload or record sound, select the prefix duration, and fit piano notes. This path never loads a TTS model.
+- **Text → speech → MIDI:** generate speech with Qwen3-TTS 1.7B VoiceDesign, then run exactly the same fitting pipeline. The default voice description is `一位温柔自信的年轻女性，声音清晰，语气亲切，表达轻快而富有感染力。` (a gentle, confident young woman with clear speech and a warm, lively delivery).
+
+Inputs are limited to 25 MB, 300 text characters, and a fitted prefix of at most 12 seconds. Longer recordings are read only through the selected prefix. New jobs share one compute queue, with at most eight queued requests. Temporary outputs are ephemeral, are cleaned after 24 hours when another job starts, and disappear when the Space restarts. Do not treat this public demonstration as private storage.
+
+## Algorithm
+
+The renderer is FluidSynth with bank 0, program 0 of the bundled MuseScore General SoundFont, fixed gain 0.8, and disabled chorus/reverb. Each candidate MIDI event has a pitch, velocity, onset and gate duration. We seek events whose **rendered sound** resembles the input, rather than merely extracting its fundamental frequency.
+
+1. Convert the input to mono at 24 kHz and normalize RMS to 0.035. Analyze magnitudes using a 2048-sample Hann STFT with 240-sample (10 ms) hops and project them onto 96 triangular frequency bands.
+2. Render a dictionary of 657 templates: pitches 36–108, velocities 45/75/105, and gate durations 60/120/240 ms. Each template includes a short release tail. Cache the dictionary by renderer configuration and SoundFont hash.
+3. Weight each band inversely to the square root of its RMS magnitude, with a floor to avoid amplifying near-silence. Greedily select a template and onset that most reduce weighted squared residual error. For residual $R$ and a shifted atom $A$, the improvement is
+
+$$
+\Delta = 2\langle R,A\rangle - \lVert A\rVert_2^2.
+$$
+
+Subtract the selected atom and forbid overlapping holds of the same MIDI pitch. Stop on nonpositive improvement or the iteration budget. The budget counts search attempts, so the accepted note count may be smaller.
+
+4. Export and decode the MIDI, then render it through the actual synthesizer. Test global velocity offsets against a log-band objective. With **Full per-note refinement**, also try each note's velocity ±10, onset ±10 ms, gate duration ±20 ms, and deletion, accepting only measured improvements:
+
+$$
+L = \frac{1}{BT}\sum_{b,t}\left|\log(1+F(y)_{b,t})-\log(1+F(S(M))_{b,t})\right|.
+$$
+
+Here $F$ is band-magnitude analysis, $y$ is the normalized target, $M$ is MIDI, and $S$ is the fixed piano renderer. The quick setting runs dictionary search and global velocity refinement; it skips the per-note sweep. The baseline rounds strong spectral peaks to piano pitches and separately calibrates global velocity.
+
+All four spectrogram panels use the same color scale. Metrics compare the input-length interval; audio includes a 0.5-second release tail. Log-band MAE is the optimization target, while spectral convergence is reported separately and need not improve. Neither metric measures speech intelligibility. Magnitude addition is only an approximation because real notes interact in phase, which motivates the renderer refinement step.
+
+The fitting core is vendored from [Speaking MIDI](https://github.com/k-l-lambda/speaking-midi/tree/932f8eb), with a portable SoundFont path and an optional quick-refinement flag. See that project for full experiments, derivations, and reproducible demo provenance.
+
+## CPU and GPU execution
+
+The Space defaults to `INFERENCE_DEVICE=cpu`. TTS uses float32 on CPU and SDPA attention; no FlashAttention or ZeroGPU decorator is required. A separate process loads only VoiceDesign for text jobs and releases its memory before piano fitting. The fitting worker also runs on CPU, even when a GPU is present. Model downloads are cached between requests on the running instance. CPU-basic hardware can take several minutes; the first request additionally downloads the model. Each worker has a 30-minute timeout.
+
+To run locally:
+
+```bash
+# Python 3.10; install libfluidsynth3, libsndfile1 and sox using your OS package manager.
+python -m venv .venv
+. .venv/bin/activate
+pip install -r requirements.txt gradio==6.17.3
+python app.py
+```
+
+Optional environment variables: `QWEN_MODEL_PATH` selects an existing local VoiceDesign snapshot; `PORT` defaults to 7860; `OMP_NUM_THREADS` defaults to 2. For GPU execution, install CUDA-compatible PyTorch/torchaudio wheels instead of the CPU wheels and set `INFERENCE_DEVICE=cuda` (or `auto` for detection). CUDA TTS uses bfloat16. The deployment targets CPU-basic and does not request GPU hardware. On 2026-10-01, Hugging Face rejected Space creation for the current account with HTTP 402: even CPU-basic Gradio hosting requires a PRO subscription. An eligible account is required to deploy; local execution works without that subscription.
+
+## Relationship to the Qwen Space
+
+The [official Qwen3-TTS Space](https://huggingface.co/spaces/Qwen/Qwen3-TTS/blob/6ae5dfa/app.py) was inspected as the backend reference. This app follows its `Qwen3TTSModel.from_pretrained(..., attn_implementation='sdpa')` and `generate_voice_design(text, language, instruct)` flow. Our backend is written separately and loads one model on demand, supports float32 CPU inference, and limits generation to 512 new tokens. We deliberately use VoiceDesign 1.7B because the 0.6B CustomVoice model does not honor natural-language voice instructions.
+
+## Assets and attribution
+
+The bundled `assets/gm.sf3` is MuseScore General v0.2, with SHA-256 `5b85b6c2c61d10b2b91cddd41efcce7b25cd31c8271d511c73afafbef20b6fa3`. See [its license](assets/MuseScore_General_License.md) for authors, MIT terms, and sample credits. Model weights remain in the upstream Qwen repository and are downloaded at runtime; they are not included here. Qwen3-TTS model license: Apache-2.0. The generated demo assets and their model revision, settings, and hashes are recorded in [examples/manifest.json](examples/manifest.json).
+
+## Deployment
+
+Authenticate using `hf auth login` or set `HF_TOKEN`, then run `python deploy.py`. The script creates `<authenticated-user>/hf-speaking-midi` and commits the application and assets to that Space. It never upgrades an account or requests paid hardware. See [validation results](VALIDATION.md) for what has actually been tested.

VALIDATION.md

+# Validation
+
+Checked on 2026-10-01 with Python 3.10, Gradio 6.17.3, Qwen-TTS 0.1.1, PyTorch 2.10.0 and FluidSynth 2.2.5.
+
+- Six automated tests passed: input validation/prefix reading, actual CPU audio fitting, both packaged examples, MIDI timing/audio round-trip, known-note dictionary recovery, and cached objective equivalence.
+- Real CPU VoiceDesign generation with float32, SDPA and the requested voice description produced a 1.12-second `Hello, piano.` clip in 8.60 seconds of generation time, excluding loading. Snapshot: `5ecdb67327fd37bb2e042aab12ff7391903235d3`.
+- Local Gradio API exercised both modes. A 0.5-second uploaded prefix with 20 search iterations completed in 7.2 seconds; text → speech → MIDI completed in 29.1 seconds, including model loading and fitting. Both ran on CPU. These are local workstation measurements, not hosted CPU-basic benchmarks.
+- Chrome/Playwright checked example loading, input mode switching and 390-pixel mobile layout. No JavaScript errors or horizontal page overflow were observed. The desktop screenshot was visually inspected.
+- Existing English and Chinese eight-second demos were generated on GPU and are labeled as precomputed. Their generation and fit provenance remain in `examples/manifest.json`.
+
+An earlier create-Space API attempt returned HTTP 402. The Space now exists at `k-l-lambda/hf-speaking-midi`; its repository was cloned on 2026-10-01 and the complete application copied into that checkout, preserving the remote history and poetry recordings. Local validation does not establish that the hosted build or inference succeeds. No subscription or paid hardware was requested.

+Thanks to Toby Smithe for helping to get Fluid included in Ubuntu.
+
+This package, of course, is the original Release 3 of Fluid.
+
+
+Fluid was constructed in part from samples found in the public domain that I
+edited/cleaned/remixed/programmed and largely from recordings of my own and
+in conjunction with the people below who helped along the way:
+
+Suren M. Seron
+Scott Hanan
+Steve Aupperle
+Chris Gillman
+Alex Taubr
+Chris Prola
+Andrew Klenk
+Winfried Hubbe
+Dylan
+Tim
+Gort
+Uros Katic
+Ethan Winer (http://www.ethanwiner.com)
+
+
+It's obviously been a few years since the project, but its nice to see that
+people are still enjoying my work and getting good use out of it.  As always,
+I'd like to hear some work done with Fluid so email me, or just email me to
+say hello and tell me what is going on in the computer musician world.
+Who knows, maybe I'll kick start this project again? ;)

+# Speaking MIDI demos
+
+Two complete Qwen3-TTS 1.7B VoiceDesign recordings are fitted with the fixed `gm.sf3` Grand Piano preset. Open [index.html](index.html) from a local checkout for audio players and an interactive MIDI piano roll. Playback and visualization work offline. Playing one track pauses the others; clicking the piano roll seeks within the fitted piano audio.
+
+| Language | Voice | Speech duration | Piano WAV duration |
+|---|---|---:|---:|
+| English | VoiceDesign | 7.84 s | 8.34 s |
+| Chinese | VoiceDesign | 7.60 s | 8.10 s |
+
+The piano files include 0.5 seconds of release tail. These are naturally generated utterances: the speech was not cropped, padded, or time-stretched to hit the target duration.
+
+## Voice design
+
+Both samples pass the following exact instruction to `generate_voice_design`:
+
+> 一位温柔自信的年轻女性，声音清晰，语气亲切，表达轻快而富有感染力。
+
+English translation: A gentle, confident young woman with a clear voice, a warm tone, and a light, engaging delivery.
+
+The model is [Qwen3-TTS-12Hz-1.7B-VoiceDesign](https://huggingface.co/Qwen/Qwen3-TTS-12Hz-1.7B-VoiceDesign). It designs a voice from the description instead of selecting the Ryan or Vivian presets used in the earlier short experiment. The installed 0.6B CustomVoice interface ignores style instructions, so the generator rejects that combination rather than silently losing the requested description.
+
+## Files
+
+Each language directory contains:
+
+- `source.wav`: original Qwen3-TTS output, 24 kHz mono, floating-point WAV.
+- `target.wav`: the same recording at the fitter's common RMS level of 0.035.
+- `baseline`, `dictionary`, and `refined`: `.wav`, `.mid`, and decoded note `.json` for each method.
+- `spectrogram.png`: target and all three reconstructions, with common display limits.
+- `piano-roll.png`: the final exported MIDI, with note velocity encoded by color.
+- `metrics.json`: measured distances, renderer identity, configuration, and repeatability.
+
+`prompts.json` contains the texts and exact voice instructions. `manifest.json` records model provenance, measured sample durations, generation settings, and SHA256 hashes for the per-language assets. The HTML page embeds the final MIDI note events so it can open locally without fetching JSON or loading any external scripts.
+
+The static piano roll uses a viridis velocity color scale, while the browser roll uses blue-to-yellow with a labeled velocity legend. Both show MIDI key-hold intervals, not the full audible decay.
+
+## Measured spectral fit
+
+| Language | Method | Notes | Log-band MAE | Linear STFT convergence |
+|---|---|---:|---:|---:|
+| English | Baseline | 457 | 0.457734 | 0.831107 |
+| English | Dictionary | 159 | 0.410655 | 0.759557 |
+| English | Refined | 148 | 0.387474 | 0.760693 |
+| Chinese | Baseline | 445 | 0.447968 | 0.831025 |
+| Chinese | Dictionary | 123 | 0.411163 | 0.770461 |
+| Chinese | Refined | 117 | 0.392300 | 0.798604 |
+
+Final log-band MAE is 15.3% lower than the baseline for English and 12.4% lower for Chinese. Refinement optimizes log-band MAE; the linear STFT metric is reported separately and need not move in the same direction.
+
+## Evaluation scope
+
+These longer samples have not received human intelligibility or ASR evaluation. Lower spectral error does not establish that the piano speaks understandable words. Recognition scores in the [research project's RESULTS.md](https://github.com/k-l-lambda/speaking-midi/blob/master/RESULTS.md) concern the earlier, shorter recordings only. All spectral metrics use the same target calibration and exclude the extra release tail beyond the speech duration. The baseline and fitted versions have different note counts.
+
+## Regenerate
+
+After installing the dependencies listed in the top-level README, repeat fitting from this Space repository:
+
+```bash
+python -m speaking_midi examples/en/source.wav --out outputs/demos/en
+python -m speaking_midi examples/zh/source.wav --out outputs/demos/zh
+python scripts/generate_speech.py --device cpu \
+  --model Qwen/Qwen3-TTS-12Hz-1.7B-VoiceDesign \
+  --samples examples/prompts.json --out outputs/new-speech
+```
+
+These commands write new outputs without modifying the committed examples. The complete demo packaging workflow is maintained in the [research repository](https://github.com/k-l-lambda/speaking-midi#readme). Use the committed `source.wav` files when comparing fitting methods on identical inputs; model/library changes can change generated speech.

+<p>Two approximately eight-second Qwen3-TTS recordings, fitted using only the Grand Piano preset in <code>gm.sf3</code>. Both use Qwen3-TTS 1.7B VoiceDesign with the same recorded voice-design instruction. Compare the speech with its piano reconstruction, then inspect the exported MIDI.</p>
+<p>Listen before revealing the transcript. Lower spectral error does not establish speech intelligibility. These longer examples have not received ASR or human listening evaluation. Playback uses saved audio; no model download or external service is required.</p>
+<details><summary>Voice description used for both languages</summary><p lang="zh">一位温柔自信的年轻女性，声音清晰，语气亲切，表达轻快而富有感染力。</p><p>This exact instruction was supplied to VoiceDesign for both recordings.</p></details>
